I bought the frame & fork today, came home and ordered some red Cinelli cable guides, thanks to the link in this thread. Looks like it's an '88 (first 3 digits are 802). Everything checked out OK: top tube passed visual inspection, plus pinging it gently with a screwdriver found no dead/rusty spots, dropouts look very good, and all 6 screws thread in and out freely.
Am I right in thinking that a vintage 3ttt stem and TdF 44 handlebar should work just dandy with this fork, as well as being an appropriate choice?
