Found for sale on eBay, vintage photo of Greensboro’s 1967 International/Boyertown Civil Defense rescue squad.
Model year is more likely 1962, as cited on this page of history about Guilford County Fire Services. It was delivered in the fall of 1962 and operated as city-county rescue unit. That said, other sources have cited the vehicle as a 1968 model.
