Sorry Peter forgot the name so had to go through both your Books to try and figure it out. They are no32 mk 1 or mk2 clicker plungers. You have the exploded view of the mk3 in your books with parts list but no exploded view of a mk2 just the parts list that I can find.They are the forth part from the right in this picture.You do have me learning .but it is slow going with out me being able to see the actual parts and them interacting with each other.
