Does anyone know anything about GBD pipes? i was given one by a friend at work. The only markings on it are GBD Virgin 1451 Made in England, it also does has a clear stem with a gold GBD logo on it. Just trying to learn more about it as i am new to pipes and he did not have much info on it. He bought it at a local estate shop along a nice longchamp that he is now using.
