55th Foot - battle of Ticonderoga

This is from the old Wolfe's Army which was a very good book that was invaluable to F&I buffs back in the Dark Ages. Nowadays its hard to keep up with all the F&I Ospreys. This image depicts the regiment in the reforms as introduced by Lord Howe. Can't find the quote about them looking droll 'like Roundheads' - maybe one of you could furnish it?
