I just happen to be an author and historian. I got into EMS when I heard my grandfather tell stories about driving a hearse as an ambulance to mine and automobile accidents in the 1950's & 1960's before the fire company picked up ambulance service in 1967. I have collected hundreds to THOUSANDS of pictures of ambulances; car chassis ambulances. 1920's - 1970's. The only thing I don't have is pictures of the insides. I'm looking for a standard list of equipment that ambulances carried before there were DOT Standards. I even have first aid and ambulance attendant text books from Pennsylvania pre-1969. I'm also looking for pictures or stories of ambulance services from the most unpopulated parts of the country, including Alaska; Nevada; all the desert areas. And pictures of the insides of the ambulances and their equipment... Or locations in the country where car chassis ambulances are still in service. The law was that, you may not put a car chassis ambulance into service after 1980 something; but if you already had one it was grandfathered in. I can post a few picture I have; I'll try that later.
