Antique Humidor questions & pictures

This Antique Humidor has been in my family for years. Nobody seems to remember whose it was.

My questions are:

1. When was it made?
2. Who made it?
3. What's it worth?
4. How was it used / copper lined?
5. Can I have a cedar box built to fit inside?
6. Who can build it for me?
7. It's in pretty bad shape, should I have it refinished?

(man, for a newbie I have a lot of questions)
