Bryant Ridge's Analysis:
The “UMBE”-marked 20-gauge shotguns attributed to the Martin workshop of Eibar, Spain, are characteristic examples of the region’s long-standing gunmaking tradition. Built in the Basque heart of Spanish firearms production, these shotguns typically feature clean external lines, solid steel barrels, and straightforward double-barrel construction suited to upland and field use. The 20-76 chamber marking indicates a 3-inch chamber, giving the gun excellent versatility with both standard and magnum 20-gauge loads. Many examples show the hallmarks of mid-century Spanish craftsmanship: well-proportioned stocks, practical bead-front sights, and good overall balance, making them comfortable to carry and quick to shoulder.

While not heavily ornamented, these shotguns often possess an understated elegance and a focus on functional performance. The barrels are usually well-regulated, providing consistent patterns, and the handling qualities tend to favor fast, instinctive shooting—an advantage for small-game or upland bird hunters. The action, wood fit, and lockup on well-preserved examples reflect the skill of Eibar’s artisans, whose work remains appreciated by those who value traditional European doubles. As a result, a Martin/UMBE 20-gauge can be a rewarding shotgun to shoot and own, offering a blend of heritage, practicality, and classic Basque gunmaking character.
