I am guessing that CD pumper is E46-2. Most of the 2nd sections organized in 1968 began using Cd rigs.
Also, the 1956 ALF shown for L106 was the same model that L27 used for years prior to getting the newer ALF as shown. I don't know if it's the same one. I do have all the rig serial numbers and unit assignments list but not accessible at the moment. Maybe someone else (like Gman or Mr. Miller) with that list can verify.
