32 Right tail light bracket...is this NOS?

[jim1932]

OK...I know there was an optional right taillight. I picked up what I was told is original left AND right. The left is definately original. This right one is certainly too heavy to be typical reproduction. The writing on it says FOLITE like it was a knock off of the duolite brand. Anyone ever see one of these? Did whitney or someone make knockoffs in the 30's and 40's?
R is stamped in where the tail light attaches (see circles).
