Norcold from 1959 Traveler

[goransons]

Helping out on a 1959 Traveler, and it has this Norcold refrigerator which I presume is original. No idea on function as of yet, but as you can see interior is not in that great of shape, nor is the brown on the outside. Certainly both could be repaired, but is it worth it? Is this a special fridge or something just likely to fail with no parts.

In less words, fix or replace?
