So a buddy brings me a 1944 Mosin and want's me to sporterize it for him. I looked it over told him I would not do it and convinced him not to mess with it by telling him that 44 is a lower production year so he should leave it be. Anyway more to the point...
I am no expert on these fine firearms by any means and found a few things I thought where weird and was wonder if you fine gents could help set me strait on some of the finer points.
I will just list the things I am wondering about over each pic.
The square shape over the date and the upside down L behind the date.
I also found it weird that the receiver Has an upside down L and a K in front of 2016 but all the other parts just have the numbers 2016.

The bottom of the receiver has what looks to be 499 on it. I have heard of old dates being down there but 499?
Also if you look to the left of the numbers I don't know that I would call it a crack but you can see what looked to be almost like an old cut (hard to see in pic).

I am guessing this is just from it being made during war time (I can tell a quality difference from my 38) but the whole length of barrel under the hand guard is ribbed like this.

Also the stock has very few markings on it and is even missing the rearsenal mark.
