There has been an ongoing discussion over recent days regarding the validity and accuracy of various pieces of BMC documents which has been enlightening for me and hopefully for others on the forum.

The final question asked of "eightfifty" which remains un answered is
"Can I assume that the authenticity and credibility such documents as BMC Technical Bulletins and BMC Service Bulletins, which were prepared by others within the organisation and not by Engineering, must be questioned as such documents did not go through the rigours of drawing office protocol.
Many people, including yourself with in your books, have and will continue to use such documents as reference points for change.

I believe it is necessary to clarify this point as it is important in the overall histroy of the product.

Things way back when were not like now, where there is a law for just about everything.

Sir Alec disagreed with a lot of things, so did something different, and look where we are today

Perfect. The more discussion and debate on things of interest to the majority the better. :)

I can confirm via photos or talking with owners the following cars have a later floorpan.
YMA2S2 29562, 29580, 30004, 31059, 31319, 33772, 34288.

Looking at my files all the cars up to YMA2S2 32773 have early wipers and all the cars after YMA2S2 32845 have later wipers. All I can say it that looking at hundreds of deluxes the wipers appear to have changed around YMA2S2 32800 in March/April 1968.

I can't get the wiper change any closer because PUB1012 says the new wiper motor started at YMA2S2 23861 and the Tech Bulletin C57/68 says it commenced at car 3280.

I am not sure why they would go back to fitting an early floorpan after fitting thousands of later floorpans.

To keep the assembly line running it may have been possible that they fitted parts from other or earlier models. An example my father owned a 66 minivan from new which had a Cooper S front pressing for the oil cooler and a bracket on the angle. I have also seen another Van with that front. I also know of a December 1970 Mark 2 Cooper S fitted from factory with beehive heater. Who knows what may have occurred to keep the assembly line going ?

That Tech Bulletin has gotta be a typo, 3280 is way back in '65.. Friday afternoon and the boss was giving the tech a hard time to get the bulletins over to the typing pool, so he just scribbled something down from his notes and out it went

I know of 2 cars (massive sample size I know) from march 67with 850 style floors. I wouldn't be surprised of there was simply a shortage of the hydro floors so they chucked the other type in instead of stopping production. Might not happen today but back then may have been a very different story.

Changeover to behave heaters seems to have happened in December '70.. I've seen a few

What floor did poverty pack models (Mini Minor and Mini 1100) have throughout their life? Since these models utilised the centre gear change (magic wand) the floor panel would obviously need a hole in this spot.

Or to ask the question another way, did any Australian pressed floor panels have the centre gear change hole?
