This a Ford C 800 Cab / John Bean (bought by FMC Food Machine Corporation) back in the late '70's early '80's ? Johnn Bean built alot of high pressure fog units, You can tell them right away because the booster reels were always covered with some heated in the colder climates.
Actually, some earlier models, at least through the mid-1960's had open booster reels in areas that didn't have really cold weather. Henrico County just outside of Richmond, Virginia, used Beans (on conventional IH chassis) in the early 1960's, all with open reels. The more telling characteristic is the chamfered rear fenders. That angled cut behind the rear compartment was standard once compartments replaced open running boards, from around 1960 through the end of production. The reel covers, whether heated or not, may have become standard in later years.
The volunteer fire dept I was on, in the early 70's, had John Bean on both of our engines. One was a Mack, the other was a Young/Ford. Each had 2 reels of 200' of 1" high pressure hose, mounted above the pump, open to the weather. Normally, they were operated at about 500-600psi, but were capable up to 1000psi, with no noticible recoil.
Backed up the Chief as a hoseman, who attacked a small shed on fire, at a railway flare fire, and the booster line did the job. Tried attacking a fully involved garage, to no effect, as the 1st engine there didn't have preconnects. Ended up protecting an adjacent exposure, till the 2nd engine arrived. It had two 1.5" preconnects, and both used, extinguished the fire, on less than 500 gallons of water. The booster hose was then used for mop up.
