One dn100cf manual gate valve
  
One low-pressure (non-rotatable) feedthru
A picture of the 'tee piece', which is indeed 6-way (but the upward facing port is dn40cf)
Downstream (left) and upstream (right) of the drift tube
 
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?
