Do you have a small utility trailer similar to the WWII Jeep trailer, that has a tailgate and a civilian ball hitch coupler?
American Central Manufacturing (ACM) supplied tubs and frames to the American Bantam Car Company for the Model T3 and also to Willys Overland Motors Inc for the Model MB-T who were both under contract during WWII to produce 1/4 ton amphibious trailers and kept parts interchangeable between the two models. Through military records we can determine how many amphibious trailers were built and when, but there currently is not any known "Official" civilian production records.
Iíve created a database where I'd like to be able to track exactly when Bantam modified existing Military Model T3 amphibious trailers which had stopped production around July 1945, and began selling a Civilian Model T3-C to the general public as a utility trailer that could be towed by the family automobile around September 1945. I do have newspaper article and ad documentation proving "Sep 1945" is accurate.
Once all the ACM parts on hand were used up, Bantam began using their own design and manufactured tubs and frames. I would also like to document when particular production changes took place in an attempt to help narrow serial number ranges which could help determine date of manufacture...the distinctive differences that are NOT just a bolt-on accessory would be the ones to identify and check on...
Look below at the various identified production changes so far and send me the data on your trailer to be added to the database.
