Just got this gem off ebay although would love to know more about it.
1980s road bike. Very light Reynolds 753 frame( 23.5") and forks, pearl white; chromed chainstay and drop-outs; Rare Ernesto Colnago chainset with original stencil cuts ( equivalent to Campagnolo Super Record); Mavic Open 4CD rims on Mavic hubs; Brazed on front changer ( Campag); Mavic rear mech and tri-bars; Campag headset, bottom bracket, and downtube levers (inscribed); Look Carbon pedals; Shimano 105 brakes; Cinelli bars; Iscaselle titanium saddle.
Virtually all components top of range ( except brakes?!) - set up as time trial bike - rear sprockets 13-21, front 53/49, and long pedal cranks ( 172.5 mm
Frame no is 360551 and has 'Tange' written underneath on Bottom Bracket
I had a look on the Classis Lightweights site and it does have the same brazing like the green frame featured.
Any help greatly appreciated
