Cartridge compatibility?

We have a power shower installed by Dolphin Bathrooms in 2003, which has a "Grasmere" mixer valve. It has recently developed a constant drip. A plumber has said that the cartridge needs to be replaced. The installation guide for the "Grasmere" states that this a "thermostatic cartridge 022801" and the line drawing in the booklet looks identical to the Aqualisa product bearing the same reference number. Can this product be used in our shower?

It may well be , but
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.

The cartridge is still in situ, but here is a scan from the installation guide, which I meant to scan with my previous e-mail. Many thanks!
