I beg to differ on barrel length. I'd bet the farm it's a 5" barrel. I had a couple of those pass through my hands. Without seeing the bore and actually testing function, "you pays yer money and you takes yer chances". If you look at sites like Gunbroker you can get an idea of market value. Up here (Canada) depending on the factors I mentioned, I'd be asking and getting between $3800-$4500.
Wow no idea these were that price. I guess my $500 bid may not be enough;-)
