I'm on a wildcat binge now and am working on several rifle projects at once, including Dubiel and Hoffman recreations. I have finding a few dead ends and was really amazed to see a 300 Hoffman barrel for sale on ebay. It was advertised as a Hoffman barrel, which I kind of doubted, as it wasn't marked that way and didn't have completely typical Hoffman contours but it was of the period and had a perfect bore and Mauser 98 threads, so I snapped it up. The seller said it had the caliber engraved on a filed flat but that was it. I haven't ever seen a caliber engraved like that on a bolt action barrel.

I put it in the shop and didn't think anything about it as I had to work several days but today I went down and unwrapped it. I thought it would be fun to find it was made by A. O. Niedner or Vernor Gipson but I'm not lucky like that. So I unwrapped it and rolled it into the light.
