Bob,
Terrific truck! I'm an American Fire Apparatus buff, own a '41 front-mount & a '51 mid-ship. your pictures are fantastic!
I agree with Tim - I've NEVER heard of a front-mount with a Mid-ship rotary. I do believe it's totally stock - all the controls on the side are pure AFA.
My mid-ship had some controls missing from the side, and a PTO lever broken off, and no PTO pump present. You may have provided the answer to what is missing! What Brand is your mid-ship? Can you find any markings on it?
On a mid-ship, it makes some sense to have a PTO-operated pump in addition to the regular, drive-shaft driven pump: It offers you pump-and-roll capability, very useful for wild fires. However, on a front-mount, especially AFAs with Barton pumps, you ALREADY HAVE pump-and-roll: It was one of there BIG selling items (lots of literature on this - search EBay for "Barton Pump" and you'll probably see some advertisements).
Only thing I can guess, is that, for some reason, the department felt they needed a Positive Displacement pump, for situations where they didn't trust the Vacuum Primer to do the job.
Speaking of which - I didn't scrutinize all of your photos; do you HAVE the kidney-shaped Barton Vacuum Primer somewhere on your truck?
-Michael
