I was going to recommend putting it up on tonton velo, but you've already done that
Good luck with it. Solving mysteries with these ancient bikes makes Egyptology child's play.
I obtained it from the guy who posted on Tonton velo. He is not that familiar with older bikes (nor am I really, but getting there), but he did not really like its ride thus his parting ways with it. No wonder since the saddle is not fit for any type of long rides due to being over broken-in and never having been re-tensioned during its life. I may be able to adjust or recondition it for further use, but for now I'll replace it with a newer Ideale in order to keep the French theme.
The rims are for roller/rod brakes as far as I can tell so either the brake style is incorrect or the wheels are wrong. Not sure if there is anything that is original to the bike itself at this point. I have the original fenders (assumed), but they are in poor condition and were apparently damaged from shipping per the previous owner.
Two other features make this different from the Automotos of that era; one being the forward mounted pump pegs (usually on the seat tube posterior), and the fork crown being of a more standard lug design as opposed to the cross tube design like on early Fiorelli/Coppi, and Raleighs. Again, I think that is an indication of a contract build making it different enough to separate it from their own marque; but that is still an assumption on my part. I have seen some Automotos with a similar fork crown, but not sure of the year(s).
