Greetings. I've been riding for too many yrs to admit on an old RB-1. A couple of weeks ago a got a Colnago master frame to build up, now I'm getting curious as to what it's vintage is.

So, for any of you Colnago historians out there here are the specifics...

* It is a red to white fade paint job. (R-W-R fade on the seat and down tubes)
* Chrome right stay
* Chrome rear dropouts
* Shaped tubes in the main triangle (top, seat and downtube) all 3 are round from the lugs and squared in the middle
* Internal rear brake cable routing
* Club shaped drain in the BB with BREV COLNAGO curving across, one word on either side of the drain
* The number 5 appears above the right dropout and 213 below
* 130mm rear spacing
* The fork is curved chrome, though I wouldn't guarantee that it is the original. I seem to remember that they had straight forks as early as '94 and the 130 spacing makes me think it is not much older than that.
* Decals look pretty cheap and show wear:
* "Master"" on both stays
* Master and Ten times World Champion on the top tube
* Colnago on both the down tube and the seat tube
* Columbus Tubing sticker on the seat tube

It also has an oddity I've never seen, there are 2 brazed on guides, one on either side of the the headtube for the shift cable housing to pass tough so it won't chafe the paint on the head tube.

TIA
