If you're sleeving damascus barrels, save the old barrels. There's an interesting story in the latest Shooting Sportsman about a guy who makes beautiful snap caps, oil bottles, and striker containers from cut off damascus barrels that would have been discarded. I don't like the idea of cutting off damascus barrels, but if it is done they could be used for secondary products. A section should also be saved for some kind of referance collection with full data on the type of gun it came from.Is there such a referance collection that anyone knows of? Maybe a project for one of the guncraft ass'n's?
