So original I wonder if it isn't better to preserve it rather than restore it. After all it will only be original once and it is in amazing condition for a 75 year old trailer. When I visited the Airstream heritage center last month I was far more drawn to the all original examples then the remade new restoration. Yes, it is nice to see what they "might" have looked like from the factory, but the real deal were the ones that went through preservation.
Just found you. Fascinating old trailer. Will be interesting to see what you make of it. Might I make a suggestion for your next vid, reconsider the jangly earrings. Although cute, noise was distracting.
