Sorry to resurrect this post folks, I have acquired a WS19 set for my Mk2 carrier now
Ron, what carrier did you use to mount the set to ?
I have had my WS set through an old hand (chap served his time on these sets) he has de commissioned the A and B sets for me by removing the associated valves, however, the intercom still works so it is my intention to use it !
I am gathering bits at the moment to complete what I need for a Mk2 install.
