Tire Cover mystery

[aacalifeer]

This spare tire cover appears to be for a large dia tire.  The cover measures 35.76 center to center on the chrome t-nuts on the face.  The tread measures 6-3/8"  Any ideas as to the application ?

I expect it will be late '30s because the tyre sits so low in the wheel well.

I am wondering if it is Huppmobile circa 1931 or 1932 (they tend to have the boxy look of the earlier "square" type of tire cover for a 1930/1931 Cadillac/LaSalle.

Not Hupmobile.

Looking at this I thought the clamp nuts would be an identifier.  Then I started wondering could it be for a continental kit, No it is not.  The tire must be a tall tire due to the size.  Any ideas ?  I have had this to several swap meets with no ID.  It is too good for the scrap yard.  But, it is too big to haul around.  If a friend would take to Hershey it might sell there.........

Bottom line, I havn't come up with ID.  Thought I'd spot it in "Crestline book of 1930-1942 American Cars"...no!

It's a nicely made factory production piece w/what appears to be orig. paint. 

Pics blow up nice; one clamp says "618  RH".......,thinking American or at least British, (but not RR.)

After looking at many fender mount covers yours is the only one that appears to flare outward towards center.

Also, I did not see any with that type dual chrome/clamp arrangement.  Rear cover seems still possible.
