History 1933-36 Ford Oval ID

What year would this 2 3/16 wide Ford oval fit? Thank you! Bob

 

Pretty sure 36

 

What's on the backside - how it's attached would narrow it down pretty quick. Manufacturer name? Any numbers? Etc.

 

It is amazing what a maroon Scotch Brite pad can reveal.

 

1935-36 have a double clip on the back to attach (cars anyway).
1932-34 are bolt on like yours, but that's about all I know about them.

Don't recall ever seeing one with the written Ford indented on the back the way yours is.
