I’ve had this old Belgian Neumann Bros hammer lock SxS 12g for many years but it wasn’t in the greatest shape, I inherited it from grandfather. I suspect it was a Sears Roebuck Catalog gun, probably a cheap one. I ran the prof marks on it once but I don’t remember the year, 1908 I think. A few years ago I took .75” off the front of the barrels to rectify a caved in barrel tip, and rest the bead. I also machined a tool to raise all the dent in the barrels. It’s got a nice set of pattern welded twist barrels on it and I thought I’d let you see what the slow rust bluing process looks like. Once the bluing is complete, I’ll etch em to bring up the twist pattern.
