Type of Finish: Blued & Case Colored

Finish Originality: Factory original, however the underside of the trigger guard appears to have been touch-up blued.

Bore Condition: The bores are bright but for a few small areas of persistent lead fowling which should clean out to reveal a bright surface. There is no erosion.

Overall Condition: This shotgun retains about 98% of its metal finish. The balance of the finish shows a few scattered scuff marks on the barrel set (of note, on the underside and left flank). The left side plate has a small amount of wear from the plate screw lever. The underside of the trigger guard’s bluing is almost purple and looks to be touch-up work; the tone variation stops just before the forward lower tang screw, there are some scrape marks under the finish. The screw heads are sharp. The markings are crisp. Overall, this shotgun rates in about Excellent condition.

Mechanics: The action functions correctly. This is a dual non-selective trigger sidelock shotgun with ejectors; the action returns to ‘safe’ when opened. The shotgun weighs 6lbs 14oz. We have not fired this shotgun. As with all used firearms, a thorough cleaning may be necessary to meet your maintenance standards.

Box, Paperwork & Accessories: None

Our Assessment: This shotgun was made in Spain by Aguirre y Aranzabal, the company has been making shotguns and rifles since 1915, this is their Number 1 model which has been around since the 1950’s. The shotgun retains about 98% of its blue and case colored finishes, the stocks have but a few minor marks, the bores are bright with no erosion and the shotgun’s engraved surfaces are of the Purdy-style with rose and scroll patterns. The metal to metal and wood to metal fit is superb, this 12 gauge should make you the talk of the range and should do well in the field. Please see our pictures and good luck.
