One low-pressure (non-rotatable) feedthru

A picture of the 'tee piece', which is indeed 6-way (but the upward facing port is dn40cf)

Reference photo (prior to AD surveyor relalignment)

Two dn160cf manual gate valves and one dn160cf pneumatic gate valve
    

Two NEG pumps; left is the one that used to be on the bottom and has a damaged connector; right is the one that used to be on the top
  

Maybe Chloé's missing scroll pump?
