The MAPF/Unique pistols are probably the highest-quality Rubys you can find. The "Manufacture d'Armes des Pyrénées Françaises" in Hendaye was located only about 50 miles from Eibar, in the Basque country on the French side of the border, and was actually founded in the 1920s by José Uria and the Arenas brothers, arms makers who had migrated from the Spanish side.

The rough hand-fitting of the WW I period was past, and unlike Eibar the company also escaped the turmoil of the Spanish Civil War, produced through the Nazi occupation, and finally closed in 2001, at least according to the rather sparse Wiki page which only exists in French and the Basque language.

"Les armes Unique furent vendues aux tireurs sportifs, aux chasseurs, mais aussi à l'Armée française, aux polices municipales, à la Police nationale, aux Douanes, à l'ONF et aux officiers de la Wehrmacht."

It's kinda cute how they stamped the caliber and the magazine capacity (9 SCHUSS means 9 shots) on the grip panel.
