I thought by now the Winchester collectors would be crawling all over you...
Unlike most Winchester model 94 rifles, this one has a number of custom features that most likely were special ordered, they include:
A pistol-grip stock with a shotgun-style buttplate.
Special figured wood (probably originally checkered).
The takedown feature.
There should be a serial number stamped on the bottom of the receiver, ahead of the lever, but back of the takedown shoulder on the barrel. An alternative possibility is that it's stamped on the bottom strap, behind the lever, or on one of the tangs. In that case it would be necessary to remove the stock to see it.
If you find the serial number, the Winchester museum in Cody, WY. would do a records search for a fee (likely around $30,00) and given that it was probably special ordered might find some interesting information about the original buyer.
The value of the rifle might depend on what they found.
