Aussie Sentinel tanks

[Mike Cecil]

Yes, Rick, the Official History account is interesting, but does not provide a complete picture by any means.

For example, the statement that the Cadillac was the 'only engine available with enough Horsepower' does not take into account the preference by Watson for the Guiberson Radial diesel engine above all others. Unfortunately, the high fees and royalties required by Guiberson were unacceptable to the Australian government, so the engine was dropped from contention. The Caddie engine in triplicate, running through a common crank-case, was the next-best available alternative.

DP Mellor's history of the AC tanks is a great starting point and a 'good read'. It's a pity that the unpublished manuscript I referred to remains just that: unpublished, as it provides a far more in-depth analysis of the whole saga.
