Hi, all these list are to try to put a date on NORMAL insignia, wings doesn't use same rules!! All the marking that you can find on Indochina era wings are on the list i put before I forgot another thing :jump school had number awarded before,so, my list is not "without errors" you can find some variant with lower or higher numbers that i put in the list But i forgot Augis marking: "INSIGNES ARTISTIQUES" "A. AUGIS" "28 M?e St BARTHELEMY" "LYON" so, your Augis wings are the perfect example of good Indochina era!! (another thing to know, number were engraved at the factory so number on Augis wings ARE ALWAYS 2,5mm high, if not it's not period made) Bouillot example drago B?ranger variant 4 Hope it's "clear" herl
