: How To Identify Your WW2 1/4 Ton  Trailer :

 Online Register and database of WW2 Jeep 1/4 ton Trailers in Australia. :

Note: In the TM Trailer Photo above right, the Trailer is missing the rear cross member. 

This may have only happened in the first batch of trailers made by Willys. If you have such a trailer, please contact me.

 

There were 12 Manufacturers of 1/4 Ton Trailers - Total Contracted 150440 Units

Here is a summary based on the contracts issued and the USA numbers issued.
There are some contract trailers that did not get a USA number. In addition,
I do not have access to the contract information on the Converto Model T6
G529 trailers. It is possible that some of the other 1945 producers did not complete their contracts also. Chuck Lutz
The information below is in flux, and wil change as new information becomes available.
