Help ID wheels

I picked these up with some other wheels and never seen them before. they measure 5x5.5 lug, 14" tire/ 6""wide. Can anyone help ID?
Thanks!

 

Can't say 100% sure, but I had a set of 14x6 that had the small holes between the lug holes just like these on a 70 scout. One guy told me that the rims were from a postal jeep, not a scout. Thats all I can say.

 

Thanks Evil, anyone else ever seen these?

 

Look to me like a farm implement wheel rim. They are usually stamped with some type of Non Highway Use.

 

How about mid-60s Imperial? They have the small hanger pin holes common to Mopar wheels which use bolts instead of nuts and what looks like wheel cover/hubcap clip mounting holes at the outside.
