Help Identifying this old speedometer!

Hey all, I recently got this speedometer in a box of parts from a garage sale, and I have no idea what make or model it went to, or what year it is from.

Anybody have any idea? Has 565DMA3 on it

Say as a young boy when my father rented a truck from UHAUL GMC or Ford and I remember looking at the 80 and 90 on how it reverted just a thought to help... Rob442 / bighorn6942

I did end up finding this old ebay listing... I think this is the exact same speedometer, so I guess it's from a 1954 Chevy truck? Anyone have any idea on this?
