The Paramedic was designed by Larry Wood. It is a fantasy design for a futuristic, high-speed ambulance.
It was first released in 1975 as part of the "Flying Colors" series. Model 7661 with Redline (RL) wheels is from that debut year.
The casting has a low, wedge-shaped design with a large, exposed mid-mounted engine under a clear cover. It features a plastic emergency light bar on the roof. The first release was in white with "Paramedic" and red cross logos.
It is thematically related to the "Emergency Squad" from the same year, representing another type of futuristic rescue vehicle.
After its Redline debut, it was produced with Blackwall wheels. It was also released in yellow.
