Ok I am new to this site, but have been reading it for years. I just bought from a big box store a unfired model 35-1 with a 4" barrel. Since 35-1 were only with 6" barrel, I am just not sure about this pistol, but it shows not sighs of being fired, and no turn marks, and everything is correct, Serial number is M407XX there are no marks on barrel pin, and a local S&W collector thinks it was a parts pistol that S&W made up from parts after the 35-1 was dropped. I am into it for $800. I am a kit gun man, so the store salesperson found this pistol back in the vault because it had been put on hold for a customer who never came back to buy it over 6 months ago. I can pay $100 for a letter, but just don't need to invest more. store will let me know if the find the box.
