Help identify CMP van body wreck

[derk derin]

Hi All,
Gord Falk & I were in the Manitoba wilderness yesterday going to look at a CMP wreck abandoned in the bush. Nothing much left of it but I was hoping it was an ambulance body for me to find a few more missing pieces for my ambulance body like the rear steps, side window frames, rear door handles, water tank, oxygen tank rack that was mounted on the ceiling etc. Turned out it wasn’t an ambulance body and there wasn’t much left of it. I scavenged as much as I could off of it but not much I could use. It was lying on its right side.
Can anybody identify what type of van body it was?
2 side windows on each side, 2 small windows at the front with 2 vents on each side of the windows. The rear doors were missing but in the pictures you can see what would have been on the roof above the rear doors is a half round opening at the top.
We managed to get a few of the U channel off of the body as some of mine on the bottom of my ambulance body is pretty rusty. I saved as many pieces that were worth saving. In one corner right beside a huge wasp nest is a shelf bracket. The floor above the rear wheel wells have hinges on them so they could be lifted up.
There was a metal reinforcing plate in the middle of the right wall in between the 2 side windows so something heavy must have been mounted on the outside wall.
Any ideas?
