Hi, Campervan newbie here.

Just bought a 1984 Talbot Express Autosleeper for a modest sum.

The bodywork is looking a bit shabby now and it's running rough but it's a great project, and I should make a few bob from it once it's up to scratch.

Does anyone know the make of this shower unit?

I'm trying to find a wiring diagram, I have a gas pilot but it doesn't fire up when water is pumped.



searches suggest it could be a vallient?

or vaillant rather.
