I have recently come across a bunch of old Stronglight and T/A chainsets that appear to be 49D's, 93's and Touristes. Some simply read "Modele Deposee" on the reverse of the spider.
I noticed that on some of said chainsets, the pedal holes are completely sealed off on the back sides like the 1958 Campagnolo chainset that recently surfaced on eBay.
I have seen many, many 49D's, mod 93's, Super Competitions, etc, over the years but never with the pedal holes completely sealed off on the reverse side. My questions are: 1. Are the Stronglight chainsets with the sealed off pedal holes an early run? And if so, 2. Approximately what year(s) were these chainsets produced? Lastly, 3. Are the Stronglight chainsets with the sealed off pedal holes more desirable to a collector (worth more) than the standard models?
