Inland 12-43 barrel, 1-44 receiver from serial #-- I imagine they're a matching original pair. "BA IAB" stock cartouche (Benicia Arsenal from what I can find). Mostly inland parts, but a couple Winchester bits in there that I've found so far. I'm not hip just yet on which parts are "correct" or "original" but I'm honestly not too concerned. Most US rifles end up in some sort of arsenal rebuilt condition so it is what it is.
I grabbed 100 rounds today after work. Hoping to shoot it some time this week. Incredibly light/handy, good sights, I can't imagine there's much recoil. I think it might end up my favorite milsurp to shoot.
