Old Mexican Coca Cola cooler

My uncle just gave me this Coca Cola cooler to fix up, I do bodywork and paint but I’m trying to figure out what model this is? It’s approx 24” long by 17” wide. There’s no markings or stamping visible. It’s actually in pretty good shape under the house paint except for the gaskets. I think this cooler is fiberglass? I haven’t started stripping off the old house paint yet. I’d like to get this back to a nice usable cooler. Just need some help finding out what model it could be, thanks!
