1917, If you get the hots for another, Grice's in Clearfield, Pa. usually has between 10-20 on the used rack.. I am guessing at that figure, but I check the used stuff there when I am in the area.. Mostly 06's, and .270's.. But some 243, 308, 7mm08, .25-06 once in a while..
I am not sure the chambered them for the .35 Whelen, but I think I may have seen a couple of those.. Will kind of miss my whitetail trip there this year..
I bet, I was in the Pittsburgh area with my dad last year and it was nice to be up there again...
