Identify cartridge

Are you able to confirm (or otherwise) thatthe crtridge in the attached photo is Bristan Regency 2/Rio Dual Control Mini Valve Cartridge - SK971007? It was difficult to turn off so I have descaled but I think the ceramic disc is no good & need to replace the unit as it is now dripping

Thank you, I have now received the part. Unfortunately when I fitted it I discovered that I had damaged the plastic part ( the ring with the 6 prongs that I assume support the thermostat piece) when I refitted the old cartridge. Am I able to get just this part from you? What part number do I order? I have fitted the new cartridge and all appears to be fine but I guess I ought to replace the plastic part.
The plastic part is shown in my original image.

The problem is that Bristan only sell this as a kit that goes with the thermostat.

However Grohe sell the identical part as a spare.
