M37 door marking question

[vargaspj]

Attached is a drawing (a picture was too big to post) of a door marking on my 1952 M37.
Under the big white Army National Star was a marking in red that was over what looks like USMC Forest Green color paint.
It is a red circle that is broken horizontally across the middle with a red "110" in block numbers in the middle.
I have spent hours looking on the internet to try to find what service/unit this marking is for.
A while back in one of the articles on historic military vehicles I was reading, there was a picture of an M37 in Vietnam with a similar marking on the door. The marking was the same but the number was different, and I remember the article mentioned that the vehicle was from a vehicle belonging to a USMC Military Police unit in Vietnam.
Does anyone have any suggestions/information on this unit marking on my truck??
BTW I could find no hood or bumper markings under the paint on this vehicle.

I just found this image after some time checking of markings and seems to belong to the 1st Military Police Battalion based in Da Nang. I don't know if this is the same image you saw.

Thank you, Sebastian!
Yes, that was the picture from the article (I can't remember what magazine the picture was in; possibly Military Vehicles Magazine?)
Anyway, it narrows it down to Vietnam and a USMC military police battalion (my M37 was also a USMC vehicle at one point; it has the "paperclips" on the fenders used for shipboard tie-down - it also has the USMC Forest Green paint as the first "base" paint color under all the other coats of paint on the vehicle).
The symbol is definitely the same; but I seem to recall that the number in the semi-circle was not the "110" that I have on the symbol on my door.
Could you make out the number in the semi-circle on your picture??
That gets me a little closer!
Thanks for the help!

Can't contribute to the question of the marking, big the pic of the Vietnam truck looks like it is parked in a salvage yard, flat tire and all. Pretty beat up truck. hal

Pat, I don't think I can improve the image more than that. I've already sharpened it when zooming on the door, and that is as far as I could get.
Maybe somebody who served on the USMC can have more ideas. I've checked a few sources and nothing.
Regarding the truck's condition, I believe the picture is a press publication from the war. Windshield is actually shot, so are the front lights. Fellas in that truck had a bad time, Hal.

I remember that pick from a long time ago and I think that truck was involved in the Tet Offensive but don't quote me on that. As for the marking...that is a USMC thing as Army MP trucks had regular bumper markings and Military Police on the truck either direct paint or on a sign attached to the truck.

I know this is an old one, but I stumbled upon these two images from Alamy site. There're dated from April 1969.
Door and tailgate markings varied in No and color between units.
Just to enrich the discussion.
