I recall scanning these pages of "The Tailor's Preceptor" from an original copy held in the textiles research library of the Royal Ontario Museum in Toronto. At the time I was interested in the correct cut of men's trousers, which this pattern shows nicely. Also, one of the book's plates shows an adjusting belt at the trouser's rear waist.
Regarding materials, note that the first page posted by Richard above states 3/4 yard of kerseymere only--no mention of any lining material.
A soldier should be as attached to, and careful of, his musket, as his mistress. (G.O. 31st December 1788, Bombay Army)
