Some for sure no. The 3 GM K is one of them.

Otherwise not too bad. Some unknowns but more the odds and erata that got punched into the receiver /barrel for production purposes.

You stock is a replacement of some mfg. They show up with some regularity and not well documented either. Heck there was a war on, guns to build and then there wasn't.

I think the various mfgs were cranking out 7000 a day at one point (that is unfathomable in that day and age and with an iffy workforce), that is a snoot full. Amazing they kept up with the known markings!

And that does not count WWII where it was, shoot, we need MORE guns. At lest not as twisted up as the 1903s, shuddder. Nice straight forward rifle, my kind.
