The one in the garage is about that time frame. I picked 1972 for some reason. Given the frame set is the same, I used the parts from my bent up Motobecane that would fit.
This picture shows the original saddle pin. the PO pulled the decals of which I have a replacement set.

Mine is beat up with lots of scratchs, rust, etc. The brakes are Mod 61. I have a set of wheels with HF Campy hubs to put on it.
I bought mine ni 2014 and paid, what I thought was too much later, at about $250. I bought it because it had chrome lugs! As purchased.

It does ride nice. Mine measures about 59cm. I never finished cleaning it up. Should do that.
