Thickness? You mean diameter?
There is no difference in thickness.

Oh I see your other thread now.
The newer 11, 12 and 13 speed (not tooth) cassette lockrings are a bit thinner than the old 8/9/10 counterparts, yes.
However it would be a shame not to use that particular lockring because it really belongs with that cassette;
they are both that lovely blue anodised colour with white highlights.
So the lockring looks correct to me.
It is a 12T small sprocket after all.
If you use an 11T lockring on a 12T cog (which is not recommended), you will/may get this kind of effect, where it is recessed:
(but nobody does this)
You will gain a few mm once you tighten the cassette.
But you either need to get the spacers and/or overlock nut dimension correct.
Are you sure there is no spacer behind the cassette?

I think I left the chain whip in the garage at my mum’s house
So might not be able to remove the cassette today

ibbz, from the initial look it looked like the diameter was a touch to small for the 12T, but you then mentioned it was not tightened.
Steel ends are thinner because they are steel compared to a lot of the Alu ones that need the bulk to stop them cracking, often with a tapered look. Not all, mainly because they can make them thinner.
I do have some thinner Alu ones from BiTD but they tend to be not a strong.
back to the other topic and get some hub pictures up etc..

Ah I thought you meant thickness
Diameter is fine as far as I can see. But the problem lies as @synchronicity said

I did say both.
Thickness was when it looked like it would bind. Problem with a phone is you can't see the detail.
What does bind mean?

Rub hard against dropout when you put the wheel in, friction stopping or slowing rotation.
