Winchester mod. 61

I went up to a friends ranch with a buddy of mine to do some quail hunting and he pulls out a gorgeous .22 pump that another friend gave him. It's a Model 61 Winchester that looks like stainless and looks almost brand new. It shoots shorts,longs and long rifles and doesn't have any way to mount a scope.
Anyone know about these?
