Found this in the KS barn and I know it's not form my T, but the square holes and rounded leading edge look kinda nice for a Bubba speedster running board. And only one found.
Before I use it as a plaque in the Man Cave, just checking here to see if this is anything "Ford" ur just a Bubbba Board.
15" long with 12" hole to hole.
I'll hang up and listen.
Early TT truck running board.
I agree with Jack... TT Truck.
And not a common part, either!
