As a Patrol truck, I would guess it is a Model 20. 50-125 gallon tank, 85 gpm aux pump. The fact it is an F-450 instead of the more common F350, I'd guess it has the "large" 125 gallon tank.
The Model 20 has been around since the late 1960s and was a very common type 6 engine with a 200 gallon tank. Since about 2000 they have primarily been used as patrol trucks limited to a max of 125 gallons of water to discourage their use as an initial attack engine.
