I cannot remember seeing any pics with a gun mounted on a step. However, in the comment below, Lester has clarified for me that guns were mounted in that position. He notes that in “the Squadron/Signal book,WWII Jeep in Action by David Doyle, there is a picture on page 41 of a maintenance crew of the 1st Armored division installing just such a mount in the exact same location.” Thanks for the detective work!
“You will not find one this complete. This one is in great shape. It is very clean. It is not a total restoration, since I like military vehicle to look like the are battle worn, not new. It needs a new paint job, which I have the paint to do it, and it comes with the jeep. This jeep is in great working order. It is in restored condition. It is not a complete restoration. It runs and drives great. Does smoke a little. All parts are here. It is a 6-volt system. Been totally rewired. All lights work. Canvas top is new. It is garage kept. Brakes are all redone, new gas tank and lines. Has medical box. The motor sounds great. The leaks are in normal spots, If not started every day will need to be primed to start. Rebuilt transmission, clutch plate. Rebuilt transfer case. Put on a new fuel pump, new distributor, new coil, and new sensors. All gauges are in working order. The is a new speedometer, so I don’t know the original miles. Brakes are new and work great…..”
