    Interesting, these are the APU’s I’m familiar with. There was a four wheeler on here not long ago. Up till then I didn’t know that type existed. I had always thought the three wheeler’s were modified from either battle/accident damaged, or otherwise intact surplus jeeps, repurposed into APU’s, not separate distinct models. I don’t remember for sure, but I think the three wheeler was rear wheel steer. Thanks for the post.

    We’ve identified three types of O’Szekeley’s (4wheel w/ bump, 3wheel w/o bump, 3wheel w/ bump) and one valentine (4wheel w/bump). It wouldn’t surprise me if there were also 4wheel w/o bump, but I just haven’t documented one yet. And, as i understand it, the 3wheel APUs were steered using the rear wheel.

    Valentine also built 3-wheeled versions as well but we have yet to find one. There’s an easy way to spot which brand is which on the 3-wheelers. A Valentine steering wheel is in the normal position, while a Szekely is mounted vertical.

    About the picture:
    “Three U.S. Navy McDonnell F2H-2 Banshee (BuNo 124971, 124972, 124982) of Fighter Squadron VF-172 Blue Bolts being serviced by maintenance personnel are on the flight deck of the aircraft carrier USS Essex (CV-9) operating off the coast of Korea.”
