Yesterday an old family friend surprised me by giving me a 1903 A3 that my grandfather, who was a gunsmith, had built years ago. He also said that one day (hopefully soon)he was going to give me a Luftwaffe drilling that my great uncle had brought back from WWII. Unfortunately years ago my uncle, who was half mean and bad to drink, sold the drilling for $65. Well, the fellow who bought the drilling never paid for it, and returned it after he had dropped it in the mud and fired it destroying the end of the barrel. I had never heard of a drilling until yesterday, and after doing some research I realized how rare and sought after it is. What are the odds that I can either find a replacement barrel, or have one built. I'm not a rich man, and the gun will never be sold since I've heard stories of my uncles exploits in WWII since I was a child and looked up to him, but I would like to replace the barrel if possible.
