The Model Nº 37 is the most famous over-and-under ever made in the Basque Country, and at one time was the most expensive shotgun made in Spain. Patterned after the celebrated German Merkel, the Nº 37 was described by the American expert, Col. Charles Askins, as “the best over-and-under made in Europe.” High praise indeed!
Like the Merkel, the Model Nº 37 employs a deep frame with bolsters and a Kersten fastening system for strength and solid lock-up. It also has a three-piece forend and a true sidelock action, with internal gold-plating as a standard feature. The locks are hand-detachable, with a hidden release.
