Can anyone give an approximate production span for the following items?
TA cyclotouriste crankset with domed nuts. The spindle has the TA trademark in the center, and the reference number (344) on one of the tapers, rather than in the center as on later models. The lockring is chunkier than the current model, and has 12 (from memory) slots. The crank fixing bolts and washers are silver colored.
Weinmann Vainqueur 999 centerpull calipers. Note: These have a curved, red label in the center, like the later models, but the label says only "Weinmann Vainqueur 999". It does not give the reach (e.g. 610, 750), but they are 750s. Also important: There are no red plastic bits or red colored metal bits whatsoever. The washers are thin stainless steel, as are the springs. The brake arms are not linked by a pin and slot, as on the later models. The fulcrums are riveted to the back plate, rather than fixed with recessed nuts.
Normandy high flange hubs with round holes and skewers marked M.M. Atom. I believe the oval holes began to appear around 1964, but there may have been overlapping production of the two styles.
Very truly yours,
