These are a couple of photos taken the very early 70's. AAA Ambulance Service (Always Alert Ambulance), used international orange on their rigs. They were based in Cupertino California, which is now home to Apple Computer. The 1967 M-M Volunteer had a Q2 on the roof, and another one under the hood. The driver would run one up to peak, and while it was coasting, would fire up the other.
