NOS replacement sheet metal often had the part number stenciled on the backside, but factory sheet metal wouldn't have any numbers on them.
Hood, doors, fenders, aprons and radiator supports to name a few pieces.
Here's an eBay ad for an NOS large opening fender. Go to the last picture and you'll see the stencil I'm talking about.
