I had one of those! Bought it from a school acquaintance who was apparently into road racing (although it turns out that a lot of his exploits were a little embellished shall we say). He had put 700c wheels on it, full length polycarbonate mudguards, a leather brooks saddle and some rubber bar covers instead of tape. Mine was the 10 speed version, with indexed shifters on the stem, and it was quite a nice bike really. I ended up selling it to a work colleague in the early 90s when I bought a mountain bike, only to find later that he didn't really use it and left it outside to rot. Shame really, would make a good project now, maybe as a resto or a single speed.
Don't remember mine having centre pull brakes though - they were considered pretty special back in the day if I remember correctly...
