I have been unsuccesful in getting into contact with Harold Dermott.
If anyone lives in his neighbourhood, maybe he can pay him a visit and ask to get into contact with me. Or even better borrow his Midas photobook (possibly hidden under his bed).
His address is (what I could find on the web):
1 Leycester Close
Windlesheim
Surrey
GU206JR
His wife has a dormant company:
Focal Point Solutions
31 Ruddleway
Longham
Oakham
LE157NZ
His son seems to be involved in a nightclub:
Club glamour puss ltd
18 Sheldons court
Winchcombe street
Cheltenham
GL522NH
Harold is the president of the Mclaren Owners Club ltd with the same address as his home.
If anyone lives nearby one of these addresses maybe they can get into contact with the Dermott family. Thanks.
