How about cottered aluminum cranks? I know of only two models: The Duprat "Maxiplume" of "Maniplume" (the exact name eludes me right now) from around 1947, and the first TA with the "pear-shaped" spindle. Any others? +++++++++++++++
Although I can't remember brand names, I do remember cottered aluminum
cranks on some horrid low-end oriental bikes. Sort of the "ride till
loose then discard" school of design, it seemed, but I was unwilling to
get too close. With all due respect (and I have not handled these
myself), some of the cognoscenti do not consider the TA to be cottered,
as the crank is not held by a friction fit between a tapered pin and the
spindle. But I don't know what they do call it...
