I bought a used Jack Taylor tandem. It came with: TA cranks, Phil hubs and diskbrake, Weinman concave rims, Cinelli new logo bars & stem, Mafac cantilevers, NR seatposts, Rallye rear deraleur, SR front. The original silver paint with box-striping is still quite nice as are the transfers.
The number stamped on the rear dropout is: 7640.
I'm guessing this is probably a 1976 bike but would like to get an exact date on the frame if possible. Any ideas or suggestions would be appreciated.
