Pull the action and see if the stock is stamped with a number that matches the action.
All Oberndorf rifles are stamped this way as far as I know.
The barrel band is not anything like I’ve seen in a TypeC or any other commercial sporter.
Show us the front sight please.
The stock looks like an early TypeB with the cheek piece - don’t think the TypeCs had a cheek piece.
The buttplate is correct for an early Oberndorf Mauser.
I think it’s a military rifles action in an early TypeB stock.
At the price it’s a nice serviceable rifle and way better than anything you could get for twice the price.
