If my memory serves me right there used to be a mid war jacket worn by Thomas Jefferson Beck of Fenners Battery in Battle Abbey, Richmond. The last time I saw it was about 25 years ago so it could be anywhere now. Worth contacting them to see if it's still in their possession. From my notes I have 5 wooden buttons on front, outer pocket on left in line with middle button, mid blue collar, body of wool? jeans.
