903.33 Cartridge

Hi, I have a Mira Excel B 1990 model shower with a fault cartridge, the 903.33 cartridge states that it will fit, but on looking at the cartridge picture it is slightly different, on the plastic black turning ring that turns the flow on/off it's shown in the picture to have ridges all the way around, yet my faulty one at home does not have these ridges it looks the same size but it's smooth all the way round, will this still fit?

Yes this will fit, that’s why it comes with a new temperature indices.
