Esperanza y Cia (ECIA) grew out of the Basque firearms tradition around Eibar, Gernika, and Markina-Xemein. The Bizkaia heritage record credits Juan Esperanza Salvador as the factory promoter, notes that he had earlier worked with Pedro Unceta in Esperanza y Unceta, and says ECIA acquired Alkartasuna pistol technology before specializing in the ECIA double-action automatic pistol and a machine gun under the same mark.
The company's long-term importance came from mortars. Basque industrial-heritage sources describe ECIA as a 1940s specialist in the manufacture and sale of mortars, while El Pais described its 1978 activity as centered on infantry mortars up to 120 mm and their ammunition. That emphasis connects directly to the cataloged ECIA L-65 mortar and ECIA 81 mm mortar grenade records.
ECIA remained active in late Cold War mortar development. In 1989, El Pais reported that the company was promoting a European mortar project involving anti-armor ammunition and that its shareholding included 40 percent ERT and 60 percent Basque defense-sector companies. By 1991, falling foreign sales and reduced Spanish defense orders had produced a suspension of payments; the Markina-Xemein facilities closed in 1994.

Esperanza y Cia is defunct, so the current ECIA-Xemein site is used only as a continuity reference for the successor formed by former workers. The included image shows a rights-clear ECIA mortar rather than surviving company facilities.
