212, You were very nearly correct regarding the AH (Previously Eurocopter) brand of Helicopters. Eurocopter was born out of an amalgamation of the German Manufacturer Messershmit Bolkow Blohm and the French Company Aerospatial. So AS not SA. Otherwise quite correct.
The EC (Now H) 135 was initially a derivative of the Military MB 105, the 108, later to become the EC135 Aimed at the Para Military market. Built in Donauworth Germany.
Aerospatial also built Military Aircraft, but tended to specialise in Civilian Helicopters like the AS350 and AS355. Mainly built in Marignan France.
