Right cartridge for HR Lava as315?

I Have a Hudson Reed Lava shower and I'm looking for a replacement cartridge. I have very little info to go on, so asking.

If you can send a photo of the valve then there is a good chance we will be able to ID it. If you can send a of photo of the valve with the knobs and covers removed, so we can see the top part of the cartridge then there is a better chance of us identifying it and if it is possible a photo of the cartridge itself as this will give us a better chance still of identifying the manufacturer.

Hi, I've attached images. This is as far as I have got in getting the cartridge out. I can't work out whether it should screw out (it feels like it doesn't want to) or if it's fixed with a locating screw into the casing of the shower or whether the chrome ring around the cartridge is so sort of cuff though how that would come off I don't know. As I said in the title the shower is a hudson reed Lava shower model As315 same as
