Brian - Thanks so much for your lovely, treasurable shot of the old girl still on the run and complete with monitor. Brings back so many memories-I recall her delivery in Nov 1954 at a cost of £8,000!
Is that a small portable pump behind the cab? If so, it looks a bit lightweight if it was there to supply the monitor. Many F17s had a built-in PTO driven Dennis No 2 500 GPM pump, which was pretty much what was needed to feed a 1.25 inch monitor 100 feet in the air!
It was frowned upon at one time to have a pump driven by the same PTO as the ladders, should it fail then the water would fail too leaving the poor guy at the top in danger
