These are the Perry militia cavalry, sold in the American AWI range but I can't see any reason why they shouldn't be used for un-uniformed Loyalists. Looking at the "British Grenadier!" scenarios, you need militia cavalry for Monmouth (4 figures), Camden (6), Petersburg (3), New Garden (20) and Cowpens (8). The last two scenarios will obviously require some additional figures from other units. There are 2 packs in the range and you can see that there are 3 basic poses in each pack: hunting shirt leaning forward, coat leaning forward and coat leaning back. The figures in the two packs have different headgear and sometimes footwear, so the figures aren't exactly the same across the packs. The right arms are separate so you can customise whether you want officers and buglers etc. I perhaps didn't vary the angle of these arms as I might have done - they are mainly pointing forward in a "charge" position.
These are nice, dynamic figures, although they are a fair bit bigger than my Eureka and Foundry AWI cavalry. The metal is quite soft, which means the swords bend easily and the horses' legs need work to straighten them out. I spent longer on the greys than I have done before, trying to capture a more realistic impression of what the coats can look like. Not much more to add, really. The 4th Continental Light Dragoons are next.
