My Colnago Technos is basically Genius tubing but drawn to Colnago's spec and named accordingly; so maybe your frame is the same but with SLX?
The curved forks indicate an early 80s date, I think. AndyP will know.
Colnago introduced straight forks in 1988.
Once Colnago were established as a brand then, as Will says, they got Columbus to make special tubing for them. Your frame might be SLX, but it was probably drawn to Colnago's spec.
Nice frame. Argos will do a good job of re-chroming. Other options are Mercian and maybe Colourtech in Dartford. I doubt you'll find anyone who'll do it for much cheaper than £80 though.
