I inherited a beautiful BPC jacket from a relative. It was made by Sheldon Kasman of Scarboro, Ont in 1983. The jacket did not come with a vest, but with two pieces of fabric that are shaped like the front part of a vest with three buttons on one piece & three buttonholes on the other. As I new member I cannot currently post a photo attachment to help explain this. Does anyone know, do these pieces get sewn to the inside of the jacket to simulate a vest? Thank you for your consideration.
