Overview
The Grande Precision Jupiter is a Spanish .32 ACP semi-automatic pistol of the Eibar 'Ruby' type, sold under the 'Jupiter' trade name owned by Etxezarraga y Abaitua y Cia and trading as Fabrique d'Armes de Grande Precision. Like other Ruby-pattern pistols it is a simple straight-blowback design copied from the FN/Browning Model 1903, with an internal hammer, frame-mounted safety and a detachable box magazine. The actual manufacture of Jupiter-marked pistols was contracted out to the Acha workshop in Eibar.

Notes
The 'Jupiter' trademark was granted to Etxezarraga y Abaitua y Cia by the Spanish government on 8 September 1922. Jupiter-branded Ruby-type pistols are comparatively scarce among the many Eibar trade names.
Background
Spain's Basque arms region flooded the early-20th-century market with cheap blowback .32 pocket pistols sold under hundreds of exotic export trade names. 'Jupiter' was one such name, registered in 1922 by the Eibar firm Etxezarraga y Abaitua y Cia, which marketed under the grand title Fabrique d'Armes de Grande Precision while quietly subcontracting the actual gunmaking to the Acha workshop.
