Gitane was a respected French Marque.
I'm surprized at the Campagnolo parts,
French bikes usually used French components
exclusively.
The rear derailleur is a either a campy
cambio corsa or a Paris roubiax system.
As much as I'd like to say I'd give ya
$100 for it, it is worth MUCH more. The cambio
corsa (if thats what it is) sells high. Last one
sold in e-bay for over $1000. If your stuff is
1st gen campy it is worth a small fortune.
How did you date bike at 1938?
Can you please post more pics, or describe
components in a little more detail?
Marty
