It has had a 'duffel cut', as evident in the photo, and the recoil pad has surely been added.

That's a very nice looking engraved 'butterknife' bolt handle which is, of course, in the Mauser location (MS is forward of the rear ring). Nice engraved grip cap, as well.

A lovely firearm, overall.

Mauser Stutzen:

Mannlicher Schoenauer Stutzen:

Both from the 1939 Stoeger catalog (US). Stoeger was the 'sole U.S. importer' of both Mauser and Mannlicher Schoenauer.

Per usinflationcalculator.com , each 1939 US Dollar would be worth $17.95 today.
The 'off the shelf' 7X57 Mauser Stutzen (with single trigger) was $148.00, or $2657.12 today (2203.48 Euro). The 6.5X57 Mauser was not offered in the '39 Stoeger.
