Had a look at Gun broker... not a pre 64 on there for under $1350 US, the earlier you get, the more they climb. $3500 US is well within the reach of an early pre 64 on the US market... the value is what you actually get for a rifle in my opinion but the asking prices give you an idea.
There are guys with money that go nuts for early Winchseter 70's, just like any other collectors.
I have a few nice toys but the one that I get the most offers on is always that pre 64 Winchester hanging over my desk... somebody obviously knows something I don't...
