Your first set of pictures looks just like what goes on my '37. I don't know what other vehicles it would fit. I am just learning this stuff myself.
The last picture is just like my '42, which came off a '41, so if would fit those two years. Probably same up to early '47 (art deco) but again don't know for sure.
