I do not set out to collect equipment but shown here is some that I have acquired along the way (and probably sold on), or photos of equipment owned by others, which gives some idea of the use of some of the valves.
I would like to add photographs of other equipment where this shows the use of the many more unusual valves in the collection. If you have any please let me know.
