Is there a small "w" on the bottom of the frame? I think it may be 1942 or 43. Just a hunch!
For those who have not delved into these old war horses. a "pre-64"...verses a "Pre War" (meaning W.W.II) can usually be determined by the stock as well as some other criteria, to include serial numbers.
Obviously, with Winchester concentrating their efforts in the early 1940's to war-demand weapons, the Model #1894 took a big back seat, rather preference aimed (Get it> "Aimed"?) at M1 Garrands and M1 30 cal. carbines.
Leftover serialized lever guns could have been "finalized" later, to that possibility we just cannot tell. One "stock" option is the stock, especially the forearm. Notice, on Warren's example, the "amount (or length)" of forearm in front of the barrel band. This is typical (in fact "all") of Pre W.W. II #1894's. I would have to dig to show a "Post W.W. II" Model #1894 as still a "Pre-64" example but this section of forearm tip is about "half" the length of Warren's example.
Hope this helps, Capt. Chris
