Identify a Dynaflow Cooler?

I found a nice Dynaflow cooler at a swap meet last weekend. My parts book only goes up to 1954, and the number is higher than what's listed for the '54 cooler, so I assume it is later. Group number is 4.128, and the Harrison tag reads 8525952. Can someone give me a year, please?

8523158 is the 55 number and that was the last year of that type cooler. Pictures?

Hi there, do you still have this cooler in Stock? Do you have fotos/pics?

I urgently need one for my Buick Special 1955.

The No on my cooler is: 8523158 55 NG

Do you want to sell it? I am in California next week (from Germany)

Maybe we can have a deal....

Cheers Mike
