identification Series MM 1951

Postby TvdWerf » Tue Oct 10, 2017 8:43 pm

One of the Dutch club members has an MM with a not complete identification plate. A Nuffield number is there and a chassis number, around 10.000 cars older as my MM.
Looks like the car details are correct for that age and number.
I start this thread for him, because he is waiting for access on this forum, he will give more information when this is ready.

Because the chassis-number is not in a straight line, our RDW is not sure about the identification from his car.
As far I know, this chassis-number can be put in the body on a later moment, is this correct?
Is there a direct link between the Nuffield number and the chassis-number?

Thank you Tvdwerf!

The main thing I need is photo's of stamped chassismumbers. (if you have a photo of the nuffield metal productions plate that would be nice to)
The stamped numbers on my MM are not really good stamped. there for I want to show photo's to proof that ist normal.

Even if there is paint over the number. the photo still means a lot to me.

Please help me out getting my MM on the road again!

There are many photos of the various types of chassis plates on the minor on the internet,

Attached are images of the stamped in numbers on the thin bulkhead strip and NMP plates.

I don't know if this is of any help to you, but I have attached a scan of a photograph of a Series MM chassis number plate. It's the type in use in 1951 and should be appropriate to your car. The numbers on the NMP plate do not relate to the chassis number. The number on the left side of the NMP plate (Z*****) should correspond with the body number, whilst the other number is a Nuffield Metal Products build number.

The scan is taken from Ray Newell's book 'Original Morris Minor' (page 36), and is of the chassis plate fitted to UK-built cars. I'm guessing your car was assembled in the Dutch plant. I don't know whether Dutch-assembled cars had a different type of chassis plate, or whether they were hand-stamped, resulting in uneven placing or spacing of the numbers.

The cars were assembled without Morris chassis plates but I think NMP plates fitted before leaving the UK? NMP and chassis plates probably not running in the correct order.

It looks like the Molenaar chassis plates were the same for all MM models as per this post from 2014

https://www.mmoc.org.uk/Messageboard/vi ... hp?t=57701

The NMP plate was on the OS bulkhead however NOT the chassis leg / tie plate.

The Molenaar Minors were CKD so the body was assembled in the UK and the rest of the build carried out in Holland. There are two fascinating films of the assembly process there.

As was suggested on the 2014 post, details may be available from the Gaydon archive.

Thank you for your reply.

The stamped chassisnumber I'm looking for is directly stamped to the bulkhead. A little under the chassisplate(5inch). There is paint over it and it's behind the big cable.

I have seen it on UK cars to. So it should be there.

What do you think it says from your close observation. Maybe Pomreg can assist from his records.

I have seen untidy stampings on the minor bulkhead numbers , so I wouldn't worry about it. I think they were probably hand stamped.
From the photo it looks to read SMM 111357. That would make it a 1951 car, which you state it is. If all the other numbers appear to fit 1951 too, then you have no problems.

Mine is the 122061, a LHD, don't know it was a CKD, but does not look like.
A little bit younger.
He has the same type of numbers, but not the SMM text.
The place is correct, and hand stamped is a possible reason for not a straight line.
When this part should be re-numbered, it is visible on the backside for sure, but I do not think so.

Normally there shouldn't be a problem. But because of the bad numbering the official thinks it's a false stamped number. That why I ask people for their mm stamped number to show the official that this is normal.

I hope some will reply with a photo.

Sending it to my email is an option to.
