ID help?

Anybody knows what this fits? Size is about 25 1/2 inches long and about 15 1/2 inches wide with about a 3/4 inch wide lip on three sides. Has cutouts for the handle and maybe a lock. The side that bolts to the truck has about a 11 inch hinge. TIA, Wayne

I didnt measure mine, but perhaps a tool box door on a deuce or 5 ton?

When I first saw it that is what I said but the M35, M39 and M809 tool box doors are way different. Wayne

The door for a tool box on the M939 series trucks.
