Winchester Model 61 22

[Offshootboy]

I just aqcuired one for free, Long story, anyway its in really good condition, its probably never even been fired and just minor surface rust on the barrel which i think i can get to come off. But i cant get the action to move at all. theres the lock button, I push that and it still wont move. what am i doing wrong? any help would be great.

any Ideas how much its worth?

Thanks Brandon
