Gentlemen, start this youtube video and then stop it at exactly 17 secs.

It's a trailer from the 1954 film, "Men of the Fighting Lady" Two of the three Navy aircraft tugs on the elevator are Jeeps converted to three wheel tractors. I first noticed these tugs when watching the film...there was a brief shot of one and I wasn't sure I had seen it correctly. I searched the internet for more pictures to confirm and found this video clip. I've never seen or heard of such a conversion before...anyone with further info regarding these interesting little beasties?
Derek.
