Galvanized Automobile Travel Cooler?

I purchased this recently and was wondering if any of you have one or have seen one. I was told it was a travel cooler for Model A Fords in the 20s. I liked it and it was in good shape so I gave it a chance. Has 2 trays that can be removed and has a small drain hole in the bottom rear of cooler. Cooler measures 34 1/2" wide x 10" deep x 8" tall. I personally don't think that is what it was but who knows! Any help would be great, thanks.
