I’ve been assembling some information on the O.E. Szekely and Associates Navy Jeeps built from CJ-3A parts. These were used to act as “Self-propelled electric power plants” on land and on battleships. They were made in three-wheeled and four-wheeled versions.

There is also a report that O.E. Szekely served 3 1/2 years in the USNR. This may have given him the contacts necessary to arrange the contract(s) for the APU Jeeps.

Some great photos from WillysArgentina of APUs

1. UPDATE: I dont’ know why I labeled this an APU. It was definitely in the Navy, but after further review, I see no reason to think it was a Szekely jeep. It is a Four wheel CJ-3A with a L-head that was listed here http://www.ewillys.com/2010/04/28/1951-navy-cj-3a-denver-co-ebay/

2. Four wheel CJ-3A APU with a F-head (and hood bump). The two extra gauges were added as well. Here are a couple pics of Tom’s jeep.

3. Three wheel CJ-3A APU with a L-head.
