Converto
Manufacturing Company in World War Two
Cambridge City, IN
1939-Present
This page updated 6-14-2022.
Converto Manufacturing is a privately-owned
company in Cambridge, IN, located at the intersection of U.S. 40 and
Indiana SR 1. Converto
currently manufactures a line of products that are used for recycling,
scrap, and waste disposal. Its main product line is material
handling equipment for this particular industry. During World War
Two, the company built 1,157 1/2-ton, two-wheel airborne trailers.
These trailers were part of a group of specially designed small pieces
of equipment that could be used by airborne engineers to prepare
airfields. The equipment was all small enough to fit into a C-47
transport or a CG-4A glider, which would bring the equipment in for
further airfield preparation. Converto, like most other American
companies, produced other products for the war effort that were not
purchased by Army Ordnance.

From both Table 1 and Table 2 it can be
determined that the 2-wheel airborne dump trailers were not built in
time to see any significant, if any, combat. They may have been
designated for the invasion of Japan that did not happen.

This Converto Airborne Trailer was on
display at the 2019 MVPA National Convention in York, PA.
According to the owner, this is one of two that he owns. He
related how he had been looking for one of these trailers for many
years, and then found this one in a field not far from where he lives in
Lexington, KY. He then related how a couple of weeks later, again
not far from his house, he found the second one. Note that the
registration number on the trailer 0878055 is shown on the original data
plate below. Author's photo.

The Case tractor shown here is a 1954
version, similar to the SI airborne tractor produced by Case during World
War Two. The original tractors are very rare, and there appears to
be only a couple still in existence. This set-up shows how the two
pieces of equipment worked together. Author's photo.

This appears to be the oldest Converto
Airborne Trailer I have found to date with a June 17, 1943, date.
It also has a separate shipping data plate. The others I have
found have all of the information on one data plate. Author's

The trailer has the original data plate and
shipping data plate attached to it. These are not reproductions.
