I don't know what it is or was, but some folks will go to a lot of trouble just to be different!

Nice one kook, We could say it's half Chevrolet.I wonder does that other ID plate indicate that this was a Factory Conversion by some outside jobber. Looks like too good of a fabricating job, for any fly by night(as G.L., would say) Hacker.Almost looks like that other tag says something about, Yellow Truck & Coach. Too bad that's not near me,I'd take a shot at it.

Should only have 1/2 of each ID plate butted together.
