You are all forgetting about the fact that the 1936 "Tokheim Parts Manual" shows the 963 as the nozzle that came with the pump. Indicentally the nozzle was made by the Milwaukee Valve Co. (not the Milwaukee Pump Co.), but Tokheim was still selling this pump in 1946 (10 years later) but they never changed their Parts Manual, it still showed the 963 as the nozzle that came with the pump. I doubt very much that MV was stil making or selling the 963 in 1946, and I doubt they were even selling the nozzle in the late 30s.
This was a nozzle left over from the visible days.
Finding the correct nozzle for the pump you have should start with when was my pump made. The 973 or the 983 may be the correct nozzle for a 36B.
