I have received a couple vintage strops where the linen piece has some sort of coating over the whole thing. The best way to describe it would be to say it looks like it was dipped in a waxy substance but it doesn't feel like wax. I don't know exactly how to describe it. I tried taking a couple pics to show what I'm talking about but don't know if they will help any. Would anyone know what is all over the linen on some old strops. This one is a C-MON 414 the linen looks to be the linen that came with the strop and the coating is under the silver leaf so I know it wasn't done after someone got the strop.
