I would bet pretty seriously on '98 Mauser.

The bolt shroud looks like it for sure. "Germanic" stock inasmuch as the side panels but the pistol grip looks too "square"...not out of the question but, to me, atypical. The spoon bolt handle definitely is in place. There are scope mounts, not necessarily incorrect, but they look real square and kinda "Weaver-ish" to me. On a rifle of the imagined sort, I would expect more of a low profile claw mount arrangement.

You saw my 8mm "Americanized Sporter" with most of the above coupled to an American stock. It looks to me like kin.

Now I gotta go watch that movie again..
