The steel hilt has improved hand protection, being of the very common "three bar" guard configuration, with a knuckle bow (the bottom guard) and two additional guards merging together and connecting to the pommel. There is a backstrap that runs the length of the grip, ending in a pommel cap with a peen button. Extending down from the backstrap are two "ears" secured to the tang by rivets. The grip is leather. Consistent with the scabbard, the Troop (H) and Sword # (7) are marked on the quillon above the backstrap.
The markings on the belt are consistent with the markings on the scabbard and hilt:
Regiment: W.Y.C.
(On Scabbard, Belt)
Troop: H
(On Scabbard, Hilt, Belt)
Sword/Trooper: 7
(On Scabbard, Hilt, and Belt)
However, the belt has the additional "Q. O. R."
This stands for:
Queen's Own Regiment
(a significant indicator, as will be mentioned later...)
DECODING THE "STORY" OF THIS SWORD
THE WORCESTERSHIRE YEOMANARY CAVALRY:

The Worcestershire Yeomanry Cavalry was raised in 1794. After the Napoleonic Wars, it was disbanded in 1827 and then re-raised in 1831, continuing on in service through the end of the century and beyond. For the purposes of this study, we are concerned with the period from 1821 through 1853 (the lifespan of the Pattern 1821 Light Cavalry sword). In this timeframe, they were not deployed outside of the country. Other than training and musters, they were employed, like other yeomanry, to deal with incidents of civil unrest that were happening in this period of social transition. Their first overseas deployment would come in the next century during the Second Boer War (1900-1903).
There were ten, 50-man troops, in the regiment, each stationed in a different town in Worcestershire. This sword was assigned to Troop H, which was stationed in Upton, and probably to trooper #7 (as marked on scabbard, hilt, and belt).
Worcestershire Yeomanry Cavalry Uniforms
From 1794 through either 1824 or 1827 (depending on the source), the W.Y.C. were in the tarleton helmet and ladder-laced tunic (above left picture). They later adopted the double breasted tunic and bell topped shako (whether that was in 1824 or when they were re-raised in 1831 depends on the source). Up to 1821 (and possibly beyond), they would have been armed with the pattern 1796 Light Cavalry saber (as is the figure in the upper left image). There is a clue to when they would have been issued the Pattern 1821...more on that in a bit.
When (then) Princess Victoria toured Worcestershire in 1832, the W.Y.C. provided the escort. In recognition of this service, when she ascended the throne, the regiment received the Royal Designation in 1837, which added the "Queen's Own Regiment" to its title.

Putting it all Together:
Authentication
(is it a fake or authentic?)
Materials and Form: The materials are all consistent with the sources. The specifications (length and configuration of blade, hilt, and overall sword) are exactly consistent with all sources.
Markings: The form and placement of markings are all consistent with what the sources indicate for the period in question. It is more usual than not for an antique sword and scabbard to not be matched. On the other hand, a matched sword and scabbard, as in this case, is not unheard of. The fact that the unit markings on the scabbard and belt are not an exact match lends credibility (the "Q.O.R." on the belt but not the scabbard) . In the case of a fake, they most likely would match.
The Vendor: This sword was obtained from a U.K. dealer in antique arms. Although this, by itself, does not ensure authenticity, it does weigh in favor of authenticity where there is any ambiguity involved as opposed to a sword acquired via ebay or a similar source.
Placing the Sword In Time:
Service Life: the service life of the sword runs from 1821 to 1853, so we can say that this particular sword was manufactured and issued sometime in that period.
Manufacturer: We know that the firm of "Harvey" in Birmingham had a long history with several different variations as the ownership shifted, but the period when it would have been "W. Harvey" was from 1816-1839, so we can narrow the timeframe further down to 1821 to 1839.
Royal Designation: We know that the regiment received the Royal Designation, "Queen's Own Regiment," in 1837. The unit stamp on the scabbard does not include the Royal "Q.O.R." designation. Given the match between sword and scabbard, we can assume that they share the same history. Thus, we can infer that this sword & scabbard are Georgian rather than Victorian, dating from before 1837.
Again, taken at face value, the belt, given that it has the "Q.O.R" stamp, dates from 1837 or after. So we can infer that the belt is later than the sword.
So far, these factors all place the sword in the 1821-1836 timeframe (post sword-pattern adoption, pre-Royal designation). But we can infer a more specific time within that range...
-----------------------
Manufacturer and Ordnance Mark Combination: If you're still reading this and recall the hint that I dropped in the discussion of the ordnance mark, here is the payoff.
Napoleonic Era Ordnance and Manufacturer's Markings
The above image is of my 1796 British Light Cavalry Saber illustrating the earlier ordnance and maker's mark combination. This sword dates from 1797-1803. During the Napoleonic Wars, the mass production of swords was done under contract by various firms (many of them based in Birmingham, Harvey being one of them--other major ones being Gill and Osborne). During this time, the colonel of the regiment, subsidized by the government, was in charge of equipping the unit. Thus, although swords were all of the same pattern they would be provided by different firms (and marked accordingly). Many swords of this period have no markings, but if marked, they usually will have the manufacturer on the spine and the government ordnance stamp on the ricasso: which was a crown over a letter.
Post 1820 Ordnance Mark: Crown over Letter over Number
After 1820, the configuration of the ordnance mark changed (as noted earlier), adding a third symbol, going from the Napoleonic crown over a letter to a crown over a letter over a number. This change was not clear cut, but took place over time. The manufacturer's names were also becoming less likely given that these firms were no longer mass producing swords and the evolving changes in acquisition.
The blade markings on this sword conform to the (early) Napoleonic combination: the manufacturer is on the spine (left) and the ordnance mark pattern is the two-part crown over letter.
Stacking this information on top of what we know of the service life of the sword and the unit history...
...we can infer that this sword falls into the Tarleton timeframe (1821-27), and within that window, is probably closer to 1821 than 1827 given the form of the ordnance stamp. As far as when the sword was actually in the hands of the W.Y.C. the most straightforward guess would be consistent with it's earlier markings: before it was disbanded in 1827. It could also be that the regiment, being yeomanry, retained its pattern 1796 swords until it was disbanded and was then issued the 1821 pattern sword when it was re-raised in 1831--from swords which had been manufactured earlier on and were in store. The royal designation was no small matter, so one could assume that the "Q.O.R." would have been added over the "W.Y.C." on the scabbard upon receiving the royal designation, although it is also possible that this was simply overlooked and not done.
We can't say for sure, but reading what is evident, and what is absent, the indicators are that the sword was most likely produced in the early 1820s, and dates no later than 1837.
BUYER BEWARE
Antique Pattern 1821 Cavalry Swords are not hard to find. More specifically, swords listed as Pattern 1821 British Cavalry Swords are not hard to find, most being officer's swords (and they are advertised as such in most cases, so no error on that score). There are also replica versions made by firms like
Kult of Athena (and others): nothing at all bad about these, but it's important to recognize them as such. The vast majority of the antique ones available are officer's swords: and there are generally always listings with these at any given time. Trooper's swords are another matter, and don't come on the market very often. Unfortunately, listings (by either design or mistake), sometimes fail to distinguish between the two, so being able to differentiate between them is important (but not difficult)...
In overall form, the officer's sword is very similar to the service sword...
The difference is the hilt. The officer's hilt ends in a stepped pommel, sometimes with a peen cap, sometimes not. The biggest difference is in the backstrap and grip: in all cases, the officer's version does not have the ear extending down from the backstrap. Furthermore, the officer's grip has wire wraps (usually silver) and is shagreen covered (the shagreen--shark skin--is no longer present on my officer's sword seen in the immediate upper left image--you can see it in the example in the upper right picture). The trooper's grip is leather with plain wire wraps; quite often, but not always, the wire wraps are missing on antique troopers swords (as is the case with the one in my possession).

The details on the hand guards are also different. The trooper's hand guard (top) are plain. The officer's hand guards are fluted (bottom image).
Finally, this pattern sword was adopted as the Royal Artillery Officer's sword in the 1830s--and is still the pattern to this day. You will see these also listed as British 1821 Light Cavalry Officer's swords, which technically they are. The artillery adopted the cavalry pattern, as opposed to having a pattern specifically designated for the artillery. So it is important to understand that there are both cavalry and artillery versions, both designated the same. The artillery officer's swords come in two lengths: the horse artillery officer's sword has the 35 1/2" cavalry blade. The foot artillery officer's sword has a 32" (or 32 1/2") blade. So if you see a sword of this pattern with a 32" or 32 1/2" blade, it is not a cavalry sword--or if it is one, it is non standard. [Addendum: according to expert Matt Easton, there was a "medium" cavalry officer's version of this sword with a 34 1/2" blade, as well as a few other variants: for more on the topic of variations, please see this piece on his
Easton Antique Arms site]
Officer's blades are also decorated with the royal cipher and other marks. Artillery swords will generally have one or more artillery symbols, most often a cannon, but also flaming bombs and clouds with lightning bolts. Having said that, other than the markings, a horse artillery officer's sword is identical to the cavalry officer's. There are also NCO versions as well. These have the officer's hilt with a plain blade (all of the NCO versions I've seen have had 32" blades: most likely foot artillery--but a cavalry NCO sword might have the 35" blade).
INFLUENCE
Although US edged weapons are generally influenced by French models, the US Ames 1833 saber was influenced by the British 1821 Light Cavalry Sword.
