French Patent # 807,506 - Idéal

French Patent 807,506 - Ideal main image

Onofre Forton of St-Étienne is named as the applicant for French patent # 848,964, which is clearly for a design known to be used by Idéal. On this, rather thin, basis, I have assumed that this patent is also for an Idéal design - although I have no other evidence for this.

This design is a classy little number - at cutting edge of fork derailleurs in 1935. I have no idea if it was ever manufactured.
