That is interesting to know about the emblem, Javier.
Quantico... I spent a day at the new museum there a couple of years ago and asked if I could speak to someone on the decal and the GPW they had there on display. They gave me the run around the whole day and did not return my request for a call back though I gave them my card and an explanation of what I wanted. I got the same brush off at MCRD in San Diego the time I visited there. I'm a pretty easy guy to talk to but they were not interested in anything but their agenda as far as I could tell.
Michigan45MB... I would sure like to know at least your first name as it is hard to envision an individual with the name of a state and model of jeep.
As far as the decal... they get painted over, sanded off... you name it. My thinking right now is the decal was only on stateside jeeps as I have not seen any photo in the field with it.
My, those are good photos.
The current magnetic decal that says United States Marine Corps is 5-3/4" in diameter... yours is about 4-3/4".
