1940's Frigidaire refrigerator

I have been posting this question at every forum I can find to try and get some info.

I have obtained a 1940’s Frigidaire refrigerator that still works. The problem is, I cannot find a copy of the manual, parts list, parts, etc. Frigidaire was a complete bust and offered no help at all. Does anyone around here know where I can find this info? It is working pretty well but would like to know more about it and also possibly replace a few parts just to be safe, i.e. door gasket, YT relay, brittle and crumbling wiring, etc.

Thanks!

There is no way you can find any original replacement parts for a such old refrigerator. Also I do not think that any manuals are still available. Maybe in some appliance musium…
