Bought this Smith Wesson revolver today and I'm not sure what I have. It's a Model 10-6, 38 SW special. However, it has a heavy barrel and I thought that wasn't available until later version (model 13). The cylinder looks mint condition. The cylinder front isn't dis-coloration. The barrel is dirty and you can tell its been fired. I would think if it was the original cylinder, it would show use. The grips aren't original. They're target grips and penciled on the inside is "L Frame'. However, stamped on the frame is the letter 'N". The serial # is D925XXX. It's nickel plated and looks to be in great shape. I didn't need another revolver but opened my big mouth and made the guy an offer which he eventually took. Now I'm wondering if I got taken to the cleaners @ 500.00. Either way, I'll enjoy a nice shooting 38 special and glad to have it in my lockbox.
