Not enough information.
None published. Try shotgun collectors.
One of innumerable guns imported from Belgian from around 1880 through 1910 for the catalog/hardware trade. Value would be below $200.
Look up the Marlin shotgun with the same model number.
Made by Ugartachea, imported late 60's into the 70's. Would sell for $300-$350
Or Brazil and ERA? Inexpensive firearm (what would you expect from Kresge) imported back when Kresge was still in business. Probably not worth over $50 if it is a single shot.
There's a whole shelf of books on firearms in your library. Or you may find information on www.savagearms.com
