The best I can tell from the shaft lenght it is for a 1951 to 1954 Kaiser. It would be a door mount. The mounting Bracket shown appears to be a A-Post mount bracket. Flip the bracket over and there should be a number stamped there. If it read 11R or 11L (Maybe just 11) then it would be correct bracket for a 1951 - 1954 Henry J and/or 1947 - 1950 Kaiser-Frazer. To properly id the soptlight itself I need a shaft lenght from the center point of the plastic handle to the pivot point of the Spotlight Lamp Housing.
