I know it’s hard with no pictures but here goes. Asking for a buddy looking at one. Serial number start with S1. He didn’t remember how many digits. I was guessing 53 to 56 since no model number. Nickel finish. He says is peeling some. 3.5 barrel. Asking price is $1000. I know it’s a broad range with not much to go on. Thank you fine gentleman for any input.
