So, after reading your remarks, i contacted the previous owner.
Indeed it was repainted. it was driven by PO in the "70's and 80's and repainted somewhere in between. It was repainted by the local company "Elmondi", hence the decal on the front tube"
So this explains the paint scheme.
PO also mentioned that it was fitted at that time in all Dura ACE components, and MAVIC rims. The Dura Ace bits are still there, even I can spot that. But are the fitted rims of the Mavic brand?
Next to that, here some pics of the underside, as i found some marks there;
56 - could that be the frame size?
and 1-0172 or L-0172. No idea on the information in this code.
And, much appreciated, i'll take note of your comments :-)
I'll clean it up, flip the brake pads, move the front derailler a tad lower & clean the chain up. Anything else?
