Good information, Greg. So if I were to do a 1964 ALF 900 Series AeroChief 90 that has a white body, by NFPA standards the frame would be white as well? According to the Syracuse Fire Department, it was powered by a 6 cylinder 305 HP engine (Continental?) hooked to a 5-speed manual transmission. The plywood roof was added in 1968 due to the Race Riots, and it was repowered in 1973 with a Detroit Diesel 6-71N/265HP. Probably when it was rebuilt with a 100ft Seagrave midship aerial ladder.
