When I bought it I was told it was surplussed from the Coast Guard. It was painted a very very light green that looked white from a distance. Under this was a semi-gloss OD Green (I found this out years later). When the light green paint became faded the "U.S. Army" stencil became visible on the hood. At this point I repainted what markings I could see and returned it to a flat OD Green.
Personally, when I was in the navy from 1982-86 I witnesses a few shore patrol jeeps that were AMC and dated from the 70's. They were painted a gloss battleship grey and had the same steel hard top that mine has.
The "US Army" and numbers "6512113" were the only markings evident when the top paint faded. The rest I added and
I do know the stars are not correct or historically accurate. The front bumper markings are my brothers unit when he was stationed at Fort Irwin CA.
