I have one in france, one in england. Both are lower end, 70's, french and blue.
On this tandem I had to upgrade spokes, rims and brake blocks this winter
I recently brought this tandem on ebay.co.uk, with stronglight cranks and normany red label hubs. My stroker is out of action for the next 9 months so there's plenty of time to work on that bike.
I do love vintage tandems, but I have yet to find a good one that is in my price range!
