I show two ads below. John Bean appears to have built both a FC-150 Model 200-F Fire Jeep, shown in the Ad below) and a FC-150 Model-FJ. I don’t know what the difference between the two is.
1. This blown up portion of the ad shows the ad for the Model 200-F from a 1960 Ad

2. This ad is from 1959. I can’t tell what model is shown. These are two of 12 pages in the brochure.
