hello, its margie, well I have been on the NAVY sites and not much luck, I called a navy recruter near my home town, he put me onto another navy petty officer who might try and help me. (I sure hope I'm doing this right) I'm still not sure how to work this computer. the plaque is: 3 1/2" by 6" at the top stamped are the words NAVY DEPARTMENT UNDER under it is the words truck-cargo 1/2 ton 4x2, then model # and some serial #, the one guy told me the long # is s n s, for ordering parts for the truck. then it tells about weight and height and width, length, and warranty, then manufactured by chevrolet division, this is a very heavy brass plaque, not something you can bend with your hand, I hope people are seeing my messages, I am kinda computer illiterate, and dont really understand this site..sorry, I appreciate all your help to me, and the kindness to me to help my son, it is very important , more than you know. love to you all and GOD BLESS
