This is my third MecaDural - it's the only one I have completef. Buying period correct parts for them is a total pita. Very difficult now to source brakes and especially 700C Lefol mudguards and decent leather saddles.
This was is a 'barn find' state when I bought it. I got it with a few others from a farm sale just north of Agen, not too far from Toulouse. There are always adverts for 'Lots Velos', but the French are very adamant not to split. So you have to buy everything! Two months of polishing and fine sanding to get it to this condition.
Mecadural were the hoors of French aluminium. They made three tube bonded alu frames under licence for everyone from Mercier, La Perle, Hirondelle right up to big boxers Peugeot. They couldn't (or weren't too bothered) to make aluminium forks to fit. But there are lots of 3rd party French fork makers like CMP Lyon, and I'm on the hunt for a pair of these right now.
