Depending on the actual condition I've seen them sell for anywhere between $ 500 to $ 850.
Rifles seen at gun shows are usually the much higher priced pieces as expected and oddly enough they do change hands.
They are a really dependable rifle when looked after and can be unexpectedly accurate.
I bought mine from an old hunter who swore by it, selling only because he was losing his eyesight.
In his mind there were no better Black Bear rifle for use in the timber.
If you should buy it I hope you are a handloader, if so you will enjoy it..
