Comments: Very early French built propeller for Caudron G3 aerial reconnaissance plane, later used as a trainer, using an 80 HP LeRhone radial engine. The numerical value of the series (1) and the serial number (109) are unusually low, indicating that this was likely a very early model from this manufacturer. In addition to the decals, Eclair propellers usually also had a stamped logo as well. The "XII" refers to a sub-type of the Caudron G3. Several "SFA" ("Service des Fabrications de l'Aviation") inspection stamps are shown, and are common on propellers of French manufacture.
