I found a razor today while checking out an antique flea market, metal top cap, bakelite baseplate and handle. It has a very unusual hump in the top cap. I found one thread with a similar razor (safety bar instead of oc) with the name slant stroke. After cleaning it gave a decent, mild shave, it was definitely the best $2 spent all day
