Winchester was in knife production from 1919-1940s. They made knives in this style. The example in this catalog page is with a higher grade handle. Has the same markings, has the same groove along the back edge. If you google winchester antique butcher knife, you'll find several examples similar to yours. Drop the word "antique" and no modern manufactured ones in that style come up.
The blade on yours looks to be as weathered as those original, pinned-handle Green River knives you have above.
Honestly, I believe you have a genuine original. It's a great item, my comment about being out of place was only directed at the Winchester branding on the blade, but looking again the marking is worn such that isn't too obvious.
