I somehow lucked out in an auction in suburban Dayton years ago. It was rainy, and the entire auction was just a few firearms. There were literally like 4 people there. A widow was selling her husbands gun stuff. I picked up a 4-digit serial number model 41 with the 7 3/8" barrel, muzzle brake, one barrel weight, and original grips in very nice condition. So that's the keeper for me. Also got some books and an unassuming looking metal toolbox chock full of parts, tools, and cleaning supplies. I sold some diopter sights, some reamers and a few other things, so all-in, I have about $500 invested in the gun and tools!
