Can't really answer your question but perhaps the following will help.
There's an airfield in the east of England called Andrewsfield. There is a lady there who can do various renewals for instructors and she does come highly recommended. Perhaps if you Googled the airfield telephone number and spoke with her, she might put you on the right track. (Subtle hint: How about a souped up Mini for a Christmas song?)
It is rather surprising how hard it is to extract this sort of information from anywhere. One wonders where do all the instructors go to renew themselves. It cannot be to the elephants' graveyard.
