I'm not 100% but i think it was a complete bike, looks amazingly similar to my 280 of 83/84. Its been advertised on ebay and elsewhere for a while, not sure why it hasn't gone as it looks like a good condition unmolested original bike. Pic of mine was just after i got it from Alans, changed the tyres from IRC 2.125/1.75 and added the bottom bracket boot but thats it
again its been a while so don't quote me but i'm sure one of the mags did a test on it at the time, probably worth asking about it on the old school race section too.
One last thing, if you buy it, do us all a favour and put those bloody bars at a proper angle!
