This was with the '49 1 ton I just bought. Maybe someone knows what it is before I am able to get it open. The hinges are stuck, I'll use heat in morning.

It has 3 pieces. They are about 8" long. They unfold open to make something. One end is wider than the other. I can't tell what the writing on side is. The holder is blocking it.

My guess: wheel chocks (not likely) or warning reflectors?
