Just had two pipes show up from eBay. The first is a BB&S Challenger (Barling Second) and the second is a GBD Prehistoric Conquest. Overall, both pipes are in decent shape. The stems will need some elbow grease and I'll want to touch up the white BB&S logo. My question for you guys is what to do about a small crack on the outside rim of the GBD? The crack does not go all the way through. What do you guys suggest?
