I think that's the correct designation.
No markings on it that I can see. with the exception of a very (very!) faint 'c' on the LH lower edge of the recv'r ring. Just above the wood line.
It's placement seems to indicate that some other markings were there as well.

8x57mm,,stepped bbl.
Single Set Trigger
Claw mounts,but no scope of course.
A prior owner started to machine a set of 1" rings for the claw bases but never got as far as actually cutting the claw feet for them. Just a solid block below the rings.

Plain stock
Looks like an old Mauser butt plate. Horn matr'l I think.

Shoots great, very accurate even with that 1943 Turk surplus ammo.
Yes I clean it afterwards as it is corrosive stuff.

For $250 I wasn't about to let it pass me by. It
s a nice shooter even if not an orig Model from the factory.

Thanks for looking..

I forgot to add that the butt stock on the RH side has an approx 2" circle cut in the wood. Looks like bout 1/8" deep.
A presentation or other incribed medalion was perhaps there at one time.
The wood inside the cut looks much cleaner and 'new' than the rest of the stock.
Also some pry marks around the edge suggesting removing what was there.
Maybe a precious metal hunter found some silver there!
