Any idea where I might be able to find a 'Sam Alia' thermostatic shower valve?

Just bought a house and the bathroom is 17+ years old - the shower valve is broken and if we can't find a replacement we'll be stuck with it until we rip the whole thing out. Not ideal when it's great condition otherwise.

Full detail is Sam Alia Mixer Thermostat ref 3008188 & 3008181
