Is anyone aware of a list of Commandants of the A&AEE, please? Wikipedia lists a few, but without dates.

Specifically, I am seeking the exact tenures of:

1. MCDONALD, Arthur William Baynes, ca 1950 to ca Aug 1952
2. WHEELER, Allen Henry, ca Aug 1952 to ca May 55
3. CHATER, Hugh Addison, ca 1957 to ca Feb 1960 (??? - This might be erroneous)
4. ROULSTON, Jack Fendick, ca Feb/Mar 1960 to ca 1964

Thanks in advance
Steve
