Data Book: page 114.
I see what Joel referred to, and it is indeed a 1950 entry. What is not so clear in the auction photos but is better hinted at in the Rebour illustration is an odd "pawl" of sorts at each end of the spindle. This seems to either wedge down into a notch in the spindle itself (in the illustration it actually appears nested onto the spindle), or else is integral with the spindle and designed to fit into the crank arm - like a single spline. The ends of the spindle are NOT square, it is a tapered cylinder. And perhaps this is why the Stronglight 49A and 49D were successful, whereas this single more delicate looking connection between crank arms and spindle may not have done well under torque. The ball bearings are shown fitted in a simple retainer cage resting against the flanges on the spindle.
Bravo ~ Good spotting, Joel!

aha!
if only my copy of the data book wasnt on loan right now - i could find
the page, but i beleive there is a rebour illustration of this very
crankset in there somewhere... the crankbolts with a cruciform
engagement pattern for the tool, the keyed, tapered spindle... its all
exactly the same...
ive been looking for confirmation that this was a magistroni design for
years now, as the commentary in le cycliste stated that it was, but i
had no way to confirm, nor anyone whod ever seen or heard of this
crankset before! so im thrilled to see this set... if i werent in the
middle of a move, id dig through my magazines and find the illustration
there, in lieu of the data book...
blast!
