Does anyone recognise this brand of shower ... I'm trying to replace the cartridge and I can't find one like it anywhere ... and no clue who makes this thing ... why don't manufacturers put their logo on things somewhere !

It is quite hefty metal so I think it's an upmarket item, the vertical pipe has little nodules that emit steam/mist into the hair/face/chest ... there's an forth tap around the left hand side that feeds another shower attachment for a douche or hand held spray but that is not attached here.

The cartridge is about 53mm long ... to the right in the picture is a threaded ring that is used to clamp the cartridge in (which sits on a male protrusion that goes into the back (top in the picture) of the cartridge by about 15mm ... there is a brass jacket/shim pipe about 25mm long that goes around the diameter of the cartridge as well ... covering the silver coloured area I guess although it's not for aesthetics ... then the chromed ring shown screws onto the brass ring and makes the item water tight (with liberal amounts of plumbers putty / ptfe) ... there's a plastic insert that protects the hot water side of the dial ... then a similar looking handle clamps onto this with a little red button to press to access the hotter water side.

I'm not sure whether the cartridge is stuffed ... or the cold water pressure is too high ... the shower water never gets as hot as one would like ... it kind of gets warm ish ... I'm used to how the cartridges work and clog up with scale too ... had them in previous homes.
