Joe Waugh ID required rebuild

[Old gh bug]

So I have just acquired this bike I was told it was a Joe Waugh I have found a frame number MS 578 this bike has been repainted at some point . I would like to restore this bike but is there anyway I could find out what the original colour is?
I haven’t started to strip it so I may find clues

MS = M Steel?

Might be some original colour on the fork steerer or hidden in the BB or inside the tubes

So, I have decided to rebuild this bike so I can use again, I have bought a few bits for it basically I have gone for Campagnolo Super Record gears etc. or should I say the parts I wanted back in the 80's but couldn't afford them but even now the prices are making me wince!
the frame i have painted and added decals. Slowly i will be building this up over the later months, so be prepared for an onslaught of build pictures
