That's a lot of nice work you've done there. I love the old Spitfire beacons. Just haven't seen one in a very long time. The last ambulance I had with a Spitfire was my '73 high top Suburban ambulance that had a Spitfire up on the high top. It had a Q over the cab along with a pair of CP25 speakers. Traded it off in '83 for our first van ambulance. Now I wish I had held onto it.
I lost a very nice 1976 Type II Dodge van ambulance in 1985 to a freak fire due to a backfire thru the carburetor. The cab area and the front tunnel lights, speakers and beacon were destroyed. But due to the partition serving as a firewall, the patient compartment suffered some heat and smoke damage, but we didn't lose any of the equipment.
That small Hotshot light I see, is that a combination blue/clear dome. Haven't seen one like that before.
