Hi...Have you tried Queensbridge Engineering, Osset Yorks? Ian

Do you mean the quick release valves which were fitted at re-furb or do you mean the adaptors which screw into the piston plate and take the pipes from the EP valve?

My bus number (if any): RM 912 & RML 2455

The pictures on the South Devon RM 1872 stuff on the main ROOF site might also help. The arrangements for the RML Refurbs still with AEC boxes are different and all sorts of odds and sods added into the airlines from the EP valve.
