Vintage 6 pack Coca-Cola 6 1/2 oz glass bottle and cardboard carrier

6 pack Coca Cola bottles with cardboard carrier, great condition. However I am unable to locate these exact bottle or carrier in any book or webpage I've seen. Bottles are all different including bottle markings. Some have Coke on one side and Coca Cola on the other and nothing on the next and some have coca-cola on both sides. Some of the bottle bottoms only have a C circled. Any info one can give on these would be appreciated.
