Last bits then:
Tonnes of pics:http://imgur.com/a/iuGqW1. C Record (2nd Gen) Crankset.
'51' date code, so 1989?
170mm, English threads.
All threads and tapers excellent/perfect. Bit of rub to the arms, but logos intact. No nicks, just light surface scratching.
Extraction bolt heads are a bit rounded (I reckon the last owner may have tried with a non-7mm hex key.) However, I will include a FREE 7mm 'Draper' Hex Key.
Needless to say, using this works perfectly well, I had absolutely no slipping/issues getting them off.
