No camera so no pics but I have an old goat uboat jacket from 1961 which has had a bit of wear and the buttonholes are in very good condition but they are the double welt type buttonholes rather than the sewn edge type that aero use.
Goat is a tough leather so i shouldn't imagine lifespan would be an issue fo any well made garment using it.
