fittings -

headset is Agrati item nr. 000.3071

pedals look to be Agrati item nr. 000.0631

chainset: if one wished it would be possible to replace the set with a tradtional three-piece one without any need for modfication. the bottom bracket shell has italian threads and is 70mm in width, although the present chainset does not use the threads. it has press-in bearing cups similar of american style one-piece chainsets.

this image shows a cottered Thompson type bottom bracket assembly (do not have an illustration of the type employed on the bicycle) -

dating -

the back side of the machine's Simplex Prestige rear derailleur may be marked with a date as here -




two other spots to check for possible date markings are the end of the handlebar beneath the handgrips and the wheel rims

Chiorda must have produced this model under many score of names for importers and chainstores as well as their own badges.

One such which came through my workshop was a Kmart AllPro bicycle.

shall be interest to read if you discover drive train to be 1/8" rather than the 3/32" one would usually expect for a derailleur system

all best wishes with it
