Thanks for the replies, yes it was the one on Ebay and ran on there for a few weeks and failed to sell. I made the guy an offer and after a bit of negotiation we agreed on a price. The car had a RWC yesterday and only needed new front disc's and everything else in in great condition so I am pretty happy. It's factory standard under the bonnet even has original air cleaner.
The front guards was the one thing that had me wondering that it may not be a Sandman but everything else seems to match Sandman. I agree with seaman that the guards may have been replaced with standard ones as GTS ones may have been unavailable or the owner didn't care if it had standard ones were used. The guy that was the original owner had it for 38 years, I will update to GTS guards anyway. The car is a factory 4 speed, M20 on the tag. Also on the tag seat capacity is stamped 2. That being the case wouldn't it have been fitted with a console and therefore have factory mounts?
