Nice! I hoped to find one in the Power Grabs box, but the only one I was able to get is carded.
I recently impulse bought a Matchbox Action Drivers hospital playset; since it was just $10. It had a decent ambulance, but a really stupid looking plastic helicopter with a spring-loaded "grabber" on the bottom that was as high as the helicopter was long. I put it aside, and got out some of my EMS models that were not properly displayed, or were overflow I had no shelf space for.
And what's displayed.
The included ambulance, which is a generic tooling dating back to 2005. It was recently retooled to be cheaper to produce after not being in the lineup for several years. The patient compartment is now plastic and the light bar was changed to be part of the windows. It's lighter than the E-350, which is built similarly, but has a metal chassis. Note the Star of Life, something they supposedly couldn't do for years; when all ambulances are so marked. While slightly stylized, it's a pretty good representation of a larger medium-duty truck chassis; used as frontline ambulances in many larger departments, or Advanced Life Support/Critical Care Transport in others.
I have no idea, but am leaning towards Dickie Toys/Majorette (it's unmarked). MBB/Kawasaki BK-117 Shock Trauma Air Rescue Service. This was a benefit model done for the agency; which serves the Canadian provinces of Alberta, Manitoba, and Saskatchewan. It was really hard to get at the time (mid-2015). A member on the diecast forum I'm on (himself a prominent model ambulance collector) knew the employee at STARS who had these done; and gave me his contact info. It came all the way from STARS Saskatoon base. Now, they're sold on the STARS website. STARS is moving to using Airbus H-145s (retiring the fleet of BK-117 and Agusta Westland AW-139s), and I'm hoping they do one of it; since there's the high-end, large scale AW-139 model, and the inexpensive BK-117. Majorette does have an EC-145 tooling, which was what it was before Airbus bought Eurocopter.
While it is just marked "STAR-"; it has the registration C-GDGP. Thus, it represents this unit, STAR-1 out of Calgary. It was featured in a scene during Season 7 in Heartland; which was why I got the model. Weird how they didn't give it a callsign. Image borrowed from Wikipedia.
Hot Wheels Unimog. Back when it was done up first as a Mortal Kombat Pop Culture issue; I tried to convert it into a unit as used by the Bundeswehr as an ambulance. I COULD NOT get the tampos off. Finally, back in the fall, they did an EMS issue, with a prominent Star of Life.
I have no idea who made it. It's probably a cheap piece from the 1980s or 1990s. But, the patient compartment is really well detailed.
Tomica Isuzu Super Ambulance. This is a bit older model, about 20 years old. It's the second tooling of this unit. The new one, on a modern Isuzu GIGA chassis, is all plastic behind the cab. On this one, only the pull-out sides are plastic. It has seen some playwear, but it's not easy to find in the US. I happened to find another collector on the diecast site I'm on selling it cheaply as a part of a playworn group of ambulances.
Maisto ambulance. Rips off the Hot Wheels ambulance from the '80s and '90s. But, it's got opening doors!
