Teardrops n Tiny Travel Trailers

I have a 1947 "All Aluminum Trailer Company" teardrop for sale. Needs total restoration or use as-is if you are adventurous or like to slum it. I am located in Palm Beach County, Florida. $850.00 firm

Note: except for the floor (wood) and the frame (steel), this trailer is all aluminum.

First off I'm not in the market. But I can't help looking and figuring what it would cost me to get one like this to rebuild rather than build new. Did a quick mileage check and you are at least 700 miles from me so I'd have a 1400 mile trip just to get there and get it back here.

And some questions.

How road worthy is it right now? Looks like it needs rear and running lights at the very least.
What shape are the tires and wheel bearings in?
What size ball does it take?
Have you got any pix of the inside and galley?

Thanks,
dave
