Mixed Shooter, is it possible to date DWM toggle assembly and Mauser frame?

Hey guys, don't forget the Mauser "hole" found on the groove of the stocklug near the top. It's pretty consistent except for "K" date frames.

Hmmm, maybe this is a 1936 Mauser frame then. Thanks Dr! With the stocks removed, on the left side of the frame I see a hole there. Right above the magazine release where the stock lug fits in the groove.

Thanks again and I'll get more pictures posted tomorrow!

Edit: more pictures...
