vixen,
What you are describing is a O/U CAPE GUN, which was very likely made in Austria or Germany. - VERY FEW 12 gauge shotguns were made in Europe for "domestic use" in the pre-WWII period, though any number were made for export to Africa, British India & the Western Hemisphere.
To me, the most important thing before firing either barrel is to have the caliber/gauge/condition CAREFULLY CHECKED by a competent smith who KNOWS European combination guns & their "quirks".
(There are at least 2-3 other possibilities in .25 calibers for the rifle barrel, other than the .25-35WCF & more than one "case length" for shotshells, too. - Also, do NOT believe the marking on these European guns; remember that Europeans were just as likely to have "modified" weapons to non-standard calibers as USA owners are.)
Inasmuch as I've NOT seen the cape-gun, nonetheless, I would guess that it's worth 1,000-2,500 USD at a fair retail price.
yours, tex
