Sandblasting my truck today, and after having it for several years in various stages of rebuilding, numbers finally came to light.
On the tailgate it had, in Yellow stenciling: USN 95-18371
On the bottom left of the tailgate, it had what looked like a hexagon, about 4" across, in yellow, with a 2 or 3 digit number on it...it was mostly gone since the USFS green had flaked off, and taken much of the yellow paint with it...but you could see the outline of the hex shape, and what looked to be numbers. Any ideas what this was??
edit: found where I had written it down, corrected the tailgate number above
