My wife's father left her his Mauser 98k when he passed 30 years ago. It's been sitting in our closet all this time and now that I'm retired, I'm finally getting around to researching what she actually has. My wife has paperwork showing this rifle was a war trophy awarded to him by the Republic of Vietnam as a token of thanks for his tour of duties in Vietnam. From my research, I'm pretty sure this rifle is a 1942 Mauser 98k manufactured at the Berlin-Lubecker factory (duv 42 d or g?). Unfortunately it's missing the bayonet, cleaning rod, and sling, but everything seems to be in working order. I'm curious if anyone has any more info this rifle. Also would love to know what the second cutout at the rear of the stock is for? I've looked at quite a few online and haven't seen this cutout before.
