Shwr Diverter Valve Slightly Passing

[Codsallian]

Does anyone recognise the brand of this shower valve? From reading other threads it seems probable that the slightly passing valve needs a new cartridge to prevent dripping when closed. The dripping has got worse over past couple years, so we have to leave shower head left on tray floor to prevenr splashing from making a mess (or keeping us awake!). If there is another solution would appreciate any advice. Tis
