Mystery wheels

I found four wheels in a storage unit that appear to be Chassis Engineering or Centerline wheels. They are 14” in diameter. Two are 12” wide and two are 14” wide. Bolt circle is 6 x 3.5.” There are no numbers or names on the wheels. These were quite popular in the 1960’s. I found images of the Caldwell D7 and D8 that apparently used similar wheels. Does anyone know what type of a vehicle might have used these?
