I've had one small US Proteus Century pass through my hands, and while your decals are a more modern style, can confirm all the details on your frame line up exactly - the seat stay points, the windowed lugs, RGF bb shell, campy dropouts, brake bridge details etc. I believe the CT part of s/n was for Century Touring

I am looking to establish if this Proteus Century model was produced in the US or in the UK and establish an age from the serial number.
The bike was purchased for the parts and is unfortunately too big for me. I am located in Johannesburg South Africa.
Here goes:
Constructed with Reynolds 531 butted tubes, stays and fork
Prugnat S/4 professional cut out lugs
RGF English thread bottom bracket
Campagnolo dropouts with eyelets and adjusters
27mm seat pin, removed a 3ttt post
Measures 58.5cm centre to top (57cm centre to centre) with 56cm top tube
Frame serial number CT673
The frame was found with Sugino Mighty BB and crank, Campagnolo NR brakes, Suntour bar-end shifters, 3ttt seat pin (saddle later junk), Tange Falcon headset and nice Japanese bar and stem.
Many thanks
