I picked up a Linkman's Fifty Grand pipe at a local antique shops. I didn't know anything about it, but since it was well smoked I figured it was worth picking up hoping it would be a good performer. I got home and did some research. What I discovered is that all Fifty Grand pipes are marked with 4 digits that should all start with 15. However mine is clearly marked 1196. Does anyone know about these pipes that can help me? Thanks.
