As a prewar (not just pre-64) Model 94 at one point it had pretty significant value. But it now has two issues.
1) As noted above, the stock and forearm are not factory original, or even Winchester in origin. And it's not very well done.
And
2) Looking at the edges on the receiver, and on the lever, it looks like it's been re-blued by someone who was not as careful as they needed to be in polishing.
I *might* in a weak moment pay $400 for it, restock, and use it as a shooter, but I would not expect to break even on the deal - even down the road. Winchester lever gun collectors are getting old and dying off. The end result is that supply is increasing, demand is falling and prices of nice Winchester lever guns are reflecting that softer market.
That leaves shooters like this with whatever intrinsic value they have as shooters - and that's around $400-$500.
