A fellow with a 20 gauge Model 21 with a hefty reserve on gunbroker, was also selling other guns, but could not measure his bores. I assumed then that he was a gunsmith rather than a collector. Little bit of humor there. How does that translate? I want seven grand for my gun but don't want to spend $100 for a choke gauge. I wonder if he would be willing to buy another one without a choke gauge?
