FWIW, plenty of small ring 98 Mausers came out of Erfurt, mostly as Kar98's (carbines).
Here's a 1917 Erfurt small ring chopper F/S;

CTK - Those small ring Model 98's were always deemed VERY desireable as the basis for a lightweight stalking/sporting rifle, due to having all the strength/safety of the gold-standard large ring Mauser 98 with a nice weight savings in both action and barrel.
A Mauser can easily be verified as being either a large ring (1.4" front ring) or a small ring (1.3" front ring) by looking at the left receiver wall -
if the left wall is flush with the front ring it's a small ring;
if the small ring additionally cocks-on-opening, it's a Model 98 small ring (and not an earlier/weaker Model 93/94/95 cock-on-closing small ring).
While I wouldn't recommend rebarreling a small ring M98 to a belted magnum, or to a cartridge needing substantive action work to accommodate it's length or width - it could be made into pretty much any standard modern chambering you'd like.
The .308 Win is well within it's parameters, as would be making a scout rifle out of it if you wished.
BTW - I've owned a few commercial Husvarna's, including one marked S&W, that were based on the small ring M98 Mauser - so if you google for those rifle's chamberings, you can see what the big boys have done.
