The AYA Nº 1 has been the flagship of the AYA line since its introduction in the late 1950s. Modelled closely on the classic Holland & Holland-style sidelock, the Nº 1 has every hallmark of the traditional English-style double: Purdey-type double underlugs, chopper-lump barrels, detachable locks, articulated front trigger, and optional self-opener. The Nº 1 is engraved in classic Purdey-style rose-and-scroll, and is stocked in fancy-grade walnut.
