my buddy called me the other day and said that he had found an 1892 in caliber 3840 that the serial number has been stamped over with some letters. He passed on the gun because of the stamp mark. I asked him what the letter spelled and he said WRACO. of course I told him to go back and buy it if the price was okay. He’s holding it for me until I can get up there in a couple weeks. He said the rifle is actually in very good shape but no serial number scared him. I think he wound up getting it for about 800 bucks. does anyone have a good source of information on these? from what I’ve read they were only done this way for a couple of years when Winchester had someone else selling their guns orta illegally?
