SNECMA
Société nationale d'études et de construction de moteurs d'aviation formed by nationalisation of Gnome et Rhône in 1945. On French engine designations even sub-series numbers (for example Gnome-Rhône 14N-68) rotated anti-clockwise (LH rotation) and were generally fitted on the starboard side, odd numbers (for example Gnome-Rhône 14N-69) rotated clockwise (RH rotation) and were fitted on the port side.
