US Government owned vehicles

[FL71C10]

I was looking at a 68 parts truck I bought for the bed and discoved a metal plate that looks like a US govt inventory tag of some sort. It's aluminum (about 3" x 3") and was riveted to the drivers side kick panel. It says "Nomenclature" on it and has basic descriptions of the truck and lists a contract # (DAAE07-68-c-1247) and has a Fed Stock # listed. I googled the contract # and DAAE07 sems like a generic US Military supplies contract code. Has anyone seen this before? I figure it must have been an army truck or maybe USAF. It's a basic shortbed stepside 6 cyl manual trans.
