Upon further inspection, I found this stamp on the front of the bolt handle, looks to me like it says "DG5"

I also noticed what may be the remains of a number on the left side of the stock, or maybe I'm just going nuts and seeing things in the wood grain...
Here are some images from various different angles and lighting. Depending on the angle it kind of looks like it says "373" or "375" and there is something that sort of looks like an "X" in front of it

There also looks to be the remains of a "7" on the right sight of the stock
