Identification III: jeeptrailers
These are the differences between a Willys MBT and a Bantam BT3. There may be more. Info and pics courtesy of dpagembt3.

A. Axle construction. The Bantam has a solid tube, with spotwelded on hubs, while a
    Willys has a weld seam in the middle. Picture of Bantam
B. The number stamped under the left front spring hanger bracket on the frame contains a "B"
     if it is a Bantam. Picture of Bantam
C. The top shock absorber attachment on a Bantam used a nut instead of a cotter key (Willys).

The biggest problem about jeeptrailers is that they continued building them after the war. Most jeepers do not know much about them, or how to identify them from WWII trailers. Neighter do I, but I am going to do some research on this topic and publish the results here. Most of this research is finding pieces of trailerstuff on other sites and compiling it here. However, the page is never complete and may contain errors, so always do your own homework if you want to buy a trailer. If you have any further information about (post) WWII jeeptrailers than please E-mail me. Info courtesy of John Hubbard.
Post WWII jeeptrailers
This is the Bantam M100. It was produced in the 1950's by a number of manufacturers, including Bratford, Dunbar Kapple and Jacques Power Saw and Motor Coach Inc. The original WWII design was updated in a number of ways:

- The 6 volts electrical system was changed to the new military 24 volts system.
- Newly designed "M" series military taillight housings replaced the WWII pattern housings.
- "M" series trailerplug replaced the WWII version.
- "Man handles" were added to all 4 corners of the body.
- The lunette was beefed up (from diameter 33 mm in WW2 to 45 mm post WW2)
- Push-button release parkingbrake changes to squeeze release.
- Tire size increased to 7.00 x 16.
- Small storage box added to frontwall of the cargobody.

A number of countries copied this trailer postwar, and all were differend in detail. Click here for a pic of a trailer used in the Dutch army for the NEKAF jeep from the 1950's onwards.
The next generation of 1/4 ton trailers was the M416. It was produced in the 1960's by the known manufacturers and a group of new ones, including Anthony, Fayette, Johnson and Furnace & Stevens. The M416 was different from the M100 in the following way:

- Track widened to follow wider (M151) vehicles.
- Traditional curved fenders were replaced by angular fenders.
- The cargo body opening was enlarged.
- Welded cargo body construction was replaced by a bolt-on design so that new bodies
   could be bolted to undercarriages as needed.
- Cast yoke changed to design allowing 2 different heights for lunette insertion. The
   lower insertion was meant fo smaller vehicles (1/4 ton) and the upper height meant
   for larger 3/4 ton towing vehicles. These insertion points were greasable and
   maintained using grease fittings.
- Safety chains were updated from the M100 design to a larger hook and a larger chain.
Click here for Jon Roger's trailer-pages. Full of info and (unique) lots of detailed pics of a restored WW2 Willys MBT Trailer. A lot of info can be found TM 10-1230 regarding the MBT, but it also covers the differences with the T-3 (reprints available). The manual for the T-3 is TM 10-1281, but this one is very rare. Info on trailers can also be found on the trailer-section of G503.com.
