Silver Birch Metallic 06968 Dulon & Duco
I had some mixed up by Alan Mance Holden who also printed a colour reference of 9KA6M(06968) on the label.
You can see this includes the code from above within it as well, but it might also help.

Can't help with the rivets though...

Interesting wheel! The early 850 wheels had the centre riveted to the rim, until around September 1961. I cannot say I know what model this is from with three rivets on the centre to locate the hub cap.

I've got 2 of these ones once cleaned up I might be able to see a date on them as they all have dates on them

Check how thick the centres are. Early rivetted ones were thin (~2mm?), too weak, and they broke, BMC then went to a thicker centre, still rivetted.
These wheels were spot welded instead from about `63 on from memory.
If I had the thin early ones now I would bin them, or hang them on the wall, they were unsafe. (I once rode an 850 to a standstill back in `65, after the centre tore right out around the 4 wheel nuts). Just after we had negotiated Galston Gorge at speed. :shock:

The very earliest 1071 Coopers had no 'bumps' to retain hubcaps on their rims. The original idea was that they were for racing so didn't need them. The problem was that they looked rubbish without hubcaps, so prior to release the factory modified all the rims by welding hubcap retainers on to them, could this be something similar?

I had a pressure pack of silver birch mixed up by my local auto paint supplier. I'd heard that there were a few different shades (there are two or three different codes listed in the colour charts). These guys only had a late '60s code, but it matched the dash of my '77 Moke really well.

The wheel above looks to have the three extrusions ('bumps') used to hold the hub cap.

This may get me into some trouble, however
If Your Car is an early 1961 it is possible it had white wheels

Yes, you're right. So not the incredibly rare 1071 wheels.

The Rivets Kev is talking about are the rivets that hold the centre to the rim, And
I would say there would be no doubt the wheel in the photo would have the centres
riveted to the rim Not welded

Umm.. Not sure if I'm missing something. But I bought some paint just the other day. Silver Birch Metallic and used the code 13260. As found here

Image

Why the differing codes?

I know they are different years but still same name????

The wheel is the same thickness as any other standard one, These are the only rivets it has the centre is welded
What about later 850 rims that are thicker like this one are they still a bin job?

Those later rivetted ones are fine, unless you are running tubeless tyres. The rivets are not leakproof like a spotweld is.

That is an early 850 wheel then, which was used to late 61. It would have been white originally as mentioned in an earlier post. These are sought after wheels. I am of the view the three studs are aftermarket and not original to the wheels (jag xj's used them too!).

The early 1071 wheels had folded tabs welded to the wheels and these had vented centres.
