Cooper S Block and Speedo Value

Post by Kiwi Craig »

What is the approx value of a Mk1 Cooper S block in the UK?

It is an AEG 312 thin flange +40 thou, has the bearing caps, not much else, no crank.
Has been stored waxed and wrapped. Still has hone hatch marks on bores.

Also the value of a Mk1 Cooper S 120 mph Speedo. Has numbers SN 4417/18 1280?

Brand new blocks have really kicked the value of original stuff.

30 years ago most S cranks were junk - full of cracks, reground 40 thou plus and that sort of nonsense. Just door stops/paperweights.
