The guns had been developed by a team under Sotiris Sofianopoulos (the origin of their basic structure is apparently connected with a Greek-Cypriot design), while existing company infrastructure had been improved to allow massive production. A relatively small number - a few more than 100 units - was produced while testing by the Hellenic Army was under way, initially indicating "positive" performance.
