Description
The “88 / Gauthier Brevete S. G. D. G. / 11 75 / Rilsan” inscription indicates that this black bicycle seat is made of Rilsan, a plastic substance derived from castor beans. Organico, a small French chemical firm, obtained a patent on the substance in 1947. In 1949, this substance, a Polyamide 11, was brought to market as Rilsan 11.
