D4, they all look to be lightly smoked. the guy had close to 250 pipes and I think he must have rotated them regularly because none of the were in bad shape.
I would say the bridge is definitely smokeable if you like big bowls. Personally It would be too much to handle for me, but I'm sure...
Recently I bought an estate lot of pipes and acquired about 50 pipes from a carver called Don Mock. Ive been trying to learn more about him and so far have discovered next to nothing via google search and other forums. Im really curious to learn about anybody who owns a Don Mock pipe or knows...
