I have looked at few of these and have to admit they handle better than their appearance suggests.
This gun is worth quite a bit because most guys that like Winchesters have disposable incomes. I would say given configuration and condition $2750+/-250. Personally I would rather buy 3" Wildfowler from the famous Birmingham Small Arms factory. Even model Deluxe with basic scroll engraving and ejectors would cost much less than field grade Model 21.
Jagermeister, this sounds like Harley-Davidson advice from one of those guys who has a Harley tattoo and a Harley tee shirt, but who does not even own a bicycle. You don't even own any doubles and frequently post your support for anti-gun politicians in Misfires. Internet Trolls win acceptance by pretending to be something they're not.
