1947 First CMP arriving to Argentina

[Bill Murray]

Hola Mariano:

I see by your postings on AACVM that you prefer to not be contacted by MP (PM in English) so I will add a few comments about myself here.

As most MLU members know, I have been doing research, as an amateur, on the subject of wheeled military vehicles (soft skins) of more or less the period 1935-1945 since the mid 1950's.

For more or less the last ten years, I have concentrated more on civilian or modified civilian cars and trucks rather than just pure military vehicles, from all countries.

For the last two years, I have been concentrating on another field of research, the sale, manufacture or assembly of North American vehicles outside of the US in the period 1930-1950. These vehicles could be civilian or military and of course CMP vehicles fit into this category.

I lived in Lima, Peru for two years, 1976-1978 so I have some knowledge of US vehicles in South America and also learned the Spanish language although I have gotten quite rusty at speaking it over the years. Also lived in Sweden 1974-1976 and Canada 1978-1980.

Regarding Argentina, I spent about a month earlier this year concentrating on that country and have about 30 bookmarks of historical websites dealing with both civilian and military vehicles in your country. For some reason, most of my photo database consists of photos of busses, I guess because there are so many "bus fan" websites.

I have just visited again the AACVM and Militariarg websites which I have not done for a while and I will remember to stay up with those sites.

Thank you again for your contribution here on MLU and other sites.

Saludos
Bill

Confused when you quote militariarg with an Argentine friend who lives in USA.
Thanks for the report on his studies about vehicles.
Very interesting contributions and information that has MLU forum and that's why I like to share with us the info i can find.
If you know my language, I invite you to register on our forum, you may need to provide good info and remove rust language!

Attach pics about the trailers behind the cmp taken the last year.





















Same trailer?

Hi Mariano

Those trailers are massive ......... they were designed for very heavy loads....... massive springs and 8 wheels.......possibly with air actuated brakes..... I do not remember ever seeing such trailers used by the Canadian army during that time.

Can only speculate that they would be of US origin and rated at 10 to 20 tons.

One of the close up of the front tow bar shows a device for locking the front axle in a forward position only ....locking the front axle from turning. Possibly and aid for backing up????

Normally CMP trailers have a small manufacturer's tag rivetted to the frame near the front left side.

Many thanks for your quick reply!
The friend who took the pictures of the trailer, found in this trailer a trailer lights socket







Maybe US made trailer as you say?
Had seen before tow bar cast as owning this trailer?

[Bob Carriere]

Here is a picture of a similar trailer socket used on USA jeep trailers.... the same connector was used on CMP at the time.

I am convinced these heavy trailers were of USA origin.

I beleive both the trailer and the truck would have had the same connector and a four wire plug/cable stretched between the two.

Thanks you Bob!

CMP factory install these trailer socket?

[Grant Bowker]

One CMP I have did have a much smaller trailer lighting socket than the one above. The small socket had only 2 electrical contacts inside. This is reasonable if the return path is through the housing of the connector because CMP trailers usually did not use electric brakes. The only wiring would be for tail lights and brake light.
I believe I have a document showing the setup for CMP trailers but will not be able to look at it until tonight.
