Hi Ian,
If it's still insured in the UK you might be better off trying one of the UK Lotus clubs, either Club Lotus or the Lotus Drivers Club. We do have some UK owners on this forum but it's a pretty diverse crowd from around the globe, so there's likely to be more chance with a UK club.
A quick look at the DVLA seems to indicate that it's still in the UK but off the road;

edit to add - if anyone else wants to find if their old cars are still on the UK roads, there is a DVLA enquiry system here :
