I have an opportunity to buy what is advertised as a late '66 1275 S. The engine number however contains a "D". Parnell's book does list 1275 S's with 9FD/SA/Y prefixes but nothing after about September 1964. What does this "D" mean and could it be right on a late '66 model?? The car is in South Africa.

Chassis number is CA2S7 932 ***
Engine number: 9FD/SA/Y 425**

Any help will be appreciated!

Hope this is helpful to you...

Thanks Canuk,

According to the info you posted, a 9FDSAY prefixed block with metal tube for the dip stick with an engine number in the late 42500's should not exist.

This number has been quoted by the owner and a third party who went to look on my behalf. I have not see it myself. I wonder if they could be confusing a / for a "D".

I am not sure but would this not indicate engine numbers after 32178....

It shows there was a 9FD/ Designation though..

Ok, I just got picture confirmation

9FD - SA - Y425**

The rivets are right next to the 9 and the last digit, touching the 9 and the last digit.

The number tag and rivets look like they've been on the car for a long time.

Also check to see if the engine has the removable tappet covers at the back of the engine....

It certainly does.

Looks nice, all the right bits there...Now just the decision to buy???

Yes, there are a few small things that need to be changed (air cleaner, spark plug caps, washer bottle, etc). The owner said the original brake master cylinder will come with the car as well.

My main concern is the authenticity of the engine number tag. Anyone who does repros and keep records of the tags they make??

Turns out there is another late '66 S on record with a 9FD-SA-Y number in South Africa, according to the records of our MOCSA historian quoted below. Weird!

"I attach a section of my "unofficial" records on Coopers in RSA starting with 932*** chassis numbers. These are 1967 or late 1966 cars. You will notice that the Cooper with chassis number C-A2S7- 892855 had a 9FD engine number. John Parnell some time ago sent me his records of CKDs Coopers dispatched for assembly in other countries. According to his records 48 Austin Cooper 'S' kits were sent between 14 October 1966 and 3 November 1966 to South Africa with 932 chassis prefixes ranging from 932272 to 932450. It seems that the 'S' that you are interested in could very well be a late 1966 model and that a 9FD engine was not common but apparently slipped in here and there as late as 1966/67 (I also have two 1965 models that have 9FD engine numbers on record)"

Whilst the characters on the tag look right the spacing of them doesn't. Can't recall having seen an S tag spaced like that before.

I agree that it looks weird. Apparently there were Coopers with 9FDSAH prefixes around at the same time. I've never seen how they are spaced. Could this be similar to the Coopers?

Another 9FDSAY....

What does the "D" stand for?
