Mauser 8mm

Mauser 8mm , I know absolutely nothing about this rifle, I took it on a trade, the bolt handle looks as tho it was welded (as seen in the picture)maybe. definitely needs some tlc, I was told that it works fine, comes with a full box of ammo, nice wood stock , and Lee reloading dies .
I’d like to get $300 cash for it , or trade it for something else. Shotgun ,or ladder stand, or trail cam that connects to your cell phone, or rifle, or something hunting related,open to offers.
