Since I posted earlier about wanting to know the source of quality parts it's only right I should contribute some knowledge to the discussion. This post is mainly about New Old Stock parts that are usually seen as the holy grail for we enthusiasts.
A Mini spares business here in Australia, Mini Kingdom Online, has quite a few New Old Stock parts that were acquired when the BMC and Leyland Australia factories closed in the early 1980's. The proprietor, John Smidt, has been running the company for 50 years so he's a very knowledgeable guy. Some of the parts are specific to Australian built Minis but he also has UK Mini parts, many as a result of the 200 complete new cars he imported from BMC UK a few decades ago. John acquired some of the Australian factory tooling and has access to original engineering drawings so parts can continue to be manufactured to factory specification. http://minikingdomonline.com.au/
John is the author of a parts catalogue for Mini and Moke models that is so useful it has been adopted by many of his competitors. It is effectively a condensed version of the BMC/Leyland Mini and Moke parts books.http://minikingdomonline.com.au/product ... mited-qty/
When my Dad was having the Mini restored while living in Singapore, back in the late 90s, I know he paid more than one visit to Mini Kingdom. I have a few receipts around somewhere
