Very interesting paper, Peter.

I zoomed in on the 1729 portrait of Viscount Dunblane and noticed what appears to be a "coxcomb" seam going up the rear of the Viscount's left leg on his truibhs. That detail also appeared on the hose in the 1680s portrait of Lord Mungo Murray. It is interesting to note that it may have continued in use into the 18th c. Is there any portrait evidence that Highland hose or truibhs continued to be constructed with this detail later than 1729?
