Mira Coda shower bar cartridge question

[scudo12]

Had issue with shower bar (previous post) , however was cheaper to replace with new shower bar.
Now I have taken the Mira off I thought to inspect it hoping to find what the issue was.
I am at the stage as per image how do I get the cartridges out, I didnt want to force anything til I got some advice.
It looks like one I have to undo the nut the other I don't see anything I can loosen to get it off.

Both ends...
Undo the nuts you can see.
The thermo cartridge is held in by the retaining ring/nut and pulls out after it's removed.
The flow cartridge is like a tap cartridge and the brass nut is part of it. It will wind out in one piece.

Flow cartridge I understand not so sure about the thermo cartridge is it that outer nut?

Yes.
It's a retaining ring.

OK thanks.

Struggling to loosen the flow nut, but will keep trying.
I just noticed this, to me it looks like a broken part, its the outlet for the shower head, any thoughts.

What makes it look broken?
Looks as I'd expect it to be to me.

Its the half moon shape, along the vertical edge not a straight line, not that I know what it should look like but looks like half maybe sheared off.

Compare it to your new one?

I'll just carry on checking the old as I have already fitted the new one so unless I take it back off I can't compare.
I'll try google for some schematics and see if I can find anything.

Thanks though for your replies.

Surely you can just remove the hose connection from the new one and take a look/photo up at the outlet?

You are correct, I was thinking to disconnect the complete bar and then have to reinstall.
I'll check that tomorrow.
Thanks for putting me right.
