Hi, Simos!
Guards & Garrisons was a brand made by John Paxton Sheriff. He was inspired to use that name from a communication from King Charles II, I think it was, in which the King referred to, "our guards and garrisons."
I can't remember his other brands, but if you search the forum for his name, you'll find at least one other thread where we talked about his toy soldiers. I know we talked about him, and there should be pictures of some of his figures in that thread.
Sheriff also wrote a book called. "Modelling Toy Soldiers". In it, he describes the process to make a figure from scratch and then cast it. Here's one link

I have a small collection of his 18th century toy soldiers, mostly grenadiers. I also have a Horse Grenadier that he did, a mounted figure, but in need of repair. The horse's head broke off at some point in the past, and I haven't gotten around to replacing it. I like them-they have a certain charm that you get with old toy soldiers.
If you can, post some pictures, please!
Prost!
