Technical Unknown Wheels

I have two of these wheels, but I can't identify them to get two more. They are 16" x 4 1/2", 5 on 5".

Any suggestions?

 

Buick and Cadillac have 5 on 5. Not sure this helps

 

I'm thinking early Dodge/Plymouth Artillery wheels. HRP

 

I have found Dodge & Plymouth Wheels 5 on 4 1/2", also found some 5 on 4 3/4" but not 5 on 5"

 

They look a lot like mid 30's Hudson wheels, but I'm not sure what bolt pattern they were. Maybe Studebaker?
