not sure of that.

Richard is right the pto will run in neutral, the countershaft is live. I have a pto on a Chev gearbox that came off a Bedford originally.

Harry, that is the case. The front gear on the cluster is "constant mesh" with the input shaft. To put your PTO into gear you put your foot on the clutch to stop the cluster turning. Other wise it is turning all the time the engine is running.
There are many vehicles with single speed transfer cases that run PTOs. As an example the WC Dodge 4x4 with winch. In fact there are many 2wd trucks without transfer cases that use a power take off to run an auxilliary of some sort.
Some gearboxes will accept 2 ptos and some transfer cases can run a pto.

To get back to the question of C15A s with PTOs - can anyone think of other C15A variants that might have used PTO other than water tank trucks? Perhaps the question should be expanded to other CMPs (both Ford and Chevrolet since many bodies were built on both chassis) that used transmission (as opposed to transfer case) PTOs?
The C60X is another likely candidate for transmission mounted PTOs since the transfer case position occupied by the PTO on C60S andC60L was used to power one of the rear axles. The C60X is an example of a transmission that could drive a PTO from either side of the transmission (but normally only used the left side opening - perhaps due to interference with the front driveshaft - only a guess)
