1938 CMP pics

[rob love]

The 1938 date would be an error, you can see the 40 on the doors, which will be the year the truck was produced.
Also, because there are 15cwt 4X4s there, and they have intake louvres, your looking at the latter part of 40 (they didn't start making 15cwt 4x4 until september if I recall) and the photo may possible be early 41.
The snow on the ground would likely limit it to at least November /December if thats in Petawawa; if it were in Manitoba it could be a bit earlier. (We have wet snow and 3 degrees C forecast in a couple of days; it was 22 here today)

Note it is mostly Chevs; the 3rd truck in the top photo is a Ford. Most of the Ford's would have been sent out West because they had a better chance of surviving in the colder climates. At least thats my theory.
