Is it a Win Model 70 rifle?

Take it to a gunsmith and have the chamber checked to see if it is a 375 H&H and was just rebarreled by J&M. I doubt its a 375 Win chambered bolt action, but who knows. And there are many other 375s (eg. Ruger, WBY, RUM), so to be sure, have it checked.

I think you're going to have to chamber cast that one. Once you determine the correct chamber dimensions you could probably rechamber to something usable.

The chamber cast could show that "it is" very useable!memtb
Possibly, but it's a wildcat of some version and who knows what brass would be required and I'm sure dies would have to be custom made. Loading data would be a challenge.
That barrel appears to taper very quickly for a heavy magnum.
I couldn't find any internet reference for 375 J&M or 375 L&M.
