coincidentally, I too have a (recently acquired) yellow Moto mixte. Probably earlier than the one above. The first digit of the ser# is very hard to read, but it may be "5", giving me a serial number of "5443092".
I'm guessing this is an early to mid 70's. The cranks are similar but the Dia-Compe brakes and RD (Suntour Vx) are newer than any of the 7-8 Peugeots I've restored. Any ideas? I'm going to do a complete tear down and mount better wheels and parts on it for someone.
