Manufactured fibers (8 %) = cholorofibers (vinyon, Rhovyl)

Note about yardage: this yarn (fmf group) dated before 1966 (date of acquisition of fmf group by the Prouvost group). Not sure there was a yardage at this time.
Do not confuse with Pernelle Espiègle (16 % mohair), the further yarn from Prouvost group.
