The 18th-century British army LOVED lace. Musicians were practically wrapped in the stuff. The 1768 Lace Book at Windsor Castle documents the official pattern of each regiment on a sample of the coat facing cloth. Roy Najecki was kind enough to document it on his website. Of course, some period paintings show different lace than the regulation--the perils of research.
The Royal Fusiliers were no exception. While they had a rather tame pattern, with only one blue stripe, their method of folding was annoyingly distinctive. As far as is known, they didn't pair their buttonholes, so there are ten equally-spaced on each coat lapel, four on each pocket flap, cuff, and back, as well as two on the collar. All but the pocket flaps and back are functional.
