Pressure Differential Warning Valve, AKA Brake fail warning

Does anyone know the origin of the brake fail warning valve on the dual circuit cars or a source of a rebuild kit for one. It looks Triumphish.

Mine worked perfectly well 38 years ago when took the car off the road and put it in storage but probably could use a rebuild before it goes back onto the car. It's hell being your own DPO. :lol:

I think it was widely used and if not available from a Lotus parts supply one of the Triumph/MG (British Victoria, Moss Motors etc) supplier will likely have it .

Thanks guys. Jackpot is right. A rebuild kit is exactly what I need. I doubt the valve gets much actual wear.
