Yeah, you always hear on Roadshow how "it would have been worth 40 billion if you hadn't fixed that wobble. But you can still get about 1000 at auction."
Or, conversely "Sure, get this fixed up and you can sell this for 50,000 dollars."
I wouldn't touch anything before having it appraised.
It's a beautiful piece. It would look lovely in my home. If it turns out to only be worth, like, a grand...and you want to get rid of it.
My old Philco needs some work done on parts of the wood, but who to trust, where to go?
