That makes total sense! Use the buttons you have plenty of available!Bryan,
I don't know a whole lot about this next pic linked below. However, it seems to be an early FIW Serjeant and 4 "Other Ranks" or "Private Soldiers." Notice the pewter 42nd Button in the center of their cockade?

I'm pretty sure you would have some kind of Cockade and button, you would attach the feathers behind on your bonnet.
And it definitely looks that way! I wonder if the buff accoutrements were just what was more widely available considering the officers wouldn't have been issued such. Perhaps they just grabbed whatever they could find when they decided to start carrying a fusil.Just looked up Captain Campbell's biography.
" In March 1762 Campbell, now a captain, exchanged into the 27th Foot, with which he served at the siege of Havana, Cuba. From the autumn of 1763 the regiment was stationed at Trois-Rivières (Que.), and in that year Campbell married Marie-Anne, daughter of Luc de La Corne, who had played an important role in French-Indian relations during the Seven Years’ War. The continuing influence of his father-in-law may have been one of the factors in Campbell’s later appointments in the Indian department."

So it seems that portrait MAY or even HAS to be right for Fort Carillon in 1758, as he transferred from the Highlanders in 1762. May be elegant proof they did use white waist coats and buff accoutrements that early?
