RE: [CR]Peugeot model names
It seems that in the beginning Peugeot just numbered their different types of bikes P1, P2, P3... P8, P9, P10,... with the P meaning simply Peugeot the order of the number meaning probably nothing. Back then the P8 was the sports/race bike with fenders and racks and the P10 the professional race bike without fenders. Then they sticked to these numbers with several additions over time indicating the level or quality: C meaning Course, L for Luxe, A for Amateur. X seemed to be a exegaration mark meaning "even more", the PL 8 was the "Luxe" model and the PLX 8 the "Grande Luxe". Maybe the X stood also for inoXidable (stainless). The number 40 and 50 were used for everyday bikes and Randonneurs with wider tires and 45 and 55 beeing the numbers for women. These had their own set of "second" characters: S for Standard, U for Utilitair,.... But the number 8 was always used for the sports race bike with fenders, often lights and racks while the 10 always stood for the pure race version without fenders or racks with the second character indicating the quality. The PH-10 was the better version of the PC-10.
My research on the "X" in PX revealed that it was meant to stand for inoxydable. Sometime in the 50's Peugeot started using the inoxydable name for its tubing and added the "X" to the name.
