Geoff - thank you for those suggestions. I bought a complete sales package of the 40/50 cars off Ebay about 6 months ago. The condition is mint and the seller's family had owned them from new. They are under lock and key along with the mint condition guarantee, driver's handbook and workshop manual that I have for 118PY. Such items never see the light of day and are opened only while wearing gloves so I can preserve them. Incidentally, they cost a lot less than the ones advertised here.
Thank you - you are great.
Regards,
Brian
