The first 4 battalions of the 60th were I believe formed from American colonists, hence the name 'Royal American Rifles'. But I think the 5th battalion was formed in Napoleonic times from British and ex-pat Germans. Have painted the jacket in a lighter green than would probably have been worn in the field, just because it looks better to me in this scale.
In the background is a Brunswick infantry regiment, came to me from ebay ready painted, just needs a little re-touching and basing. Only 20 strong though, including 2 officers, and the HH catalogue from 1973 indicates MH never did musicians or standard bearers. Anybody know if DK did Brunswick command figures?
