CMP identification - combined operations film (1943)

[Alan McGuinness]

It's a gun portee. A few frames later there's a good rear view where you can see the loading/unloading ramps stowed vertically.

There are several threads on these vehicles, such as this one: http://www.mapleleafup.net/forums/showthread.php?t=6683 and an extensive article in Wheels & Tracks #33.
