Oh, I missed the 100 Euros. I was concentrating on the photos.
The frame will sell on E-Bay for around $300 - $400 + shipping, even in fairly rough shape. Especially for the early 70's models.
Crankset, derailleurs, bottom bracket, headset, brakes, and hubs, and you have another $300 or so.
You don't have it in your garage or basement already?
Hmmm...
Packing Tape is a nice touch...
I am curious if THAT bike has Downtube water bottle boss braze-ons.
That could be a mess to deal with, but if you are planning to repaint, you can deal with the bottle bosses at the same time.
