I´ve found an advertisement in a french 1926 magazine that leaves some questions open.
My french is minimal, so maybe some of our french or franco-canadian autopuzzlers may be able to help me with it:
may "fibro-liege" (Light fibres?) be kind of a Duroplast, a form of plastic containing resin strengthened by wool or cotton fibres like the Trabant did use some decades later, too?
The only piece of text I´ve found that might be in relation to it said that a french company called Nagal had used the so called "Fregoli"-system for some 1920´s Fords
It would be great if someone could tell me something reliable about Nagal or Fregoli...
