French Aluminum cottered crank arm

This French aluminum cottered crank arm was manufactured after WWII in the late 1940s. Stronglight had already been manufacturing aluminum cotterless cranks for over a decade, so it seems a little strange that manufacturers didn't all move toward using square taper crankarms over cottered. All that said, TA did introduce their Criterium crankset that employed a cotterpin-like system on a pear shaped spindle around 1961, well after Campagnolo had started producing their iconic Record crankset using a square tapered spindle.
