ACHA, Domingo and Fernando
The mark “Longines” on pistols of Basque manufacture was deposited under the n° 74302 by the ACHA, Domingo and Fernando, in Ermua (Vizcaya), and this, in 1920.
Their company dates from the beginning of the years 1910, at the origin under the denomination “Pedro Maria Acha Hermanos”. They are also the “authors” of famous “Looking Glass”, inter alia.
“Longines” corresponds to an automatic pistol of gauge 7,65 having a “certain resemblance” to the FN-Browning 1910… (Which had believed it!)
