Mike,
Wow, you guys are great, what a great direction to pursue. The information you guys have supplied is fantastic. I will post on the outcome when I have completed my search and thoroughly covered all the new info you have taken the time to relay to me.

It's very collectable, worth maybe $10K or more.
The group you want to contact isthe MBSI (Music Box Society International) (a.k.a. Mighty Big Spenders )
We have a Web site, tho I don't have it handy.
Most MBSI members would buy the Symphonion and put up with the other "stuff" that you have. I'm sure you'll find a willing buyer for it, especially if it's in playing condition, as they often are (no leather bellows or pads to go bad, but springs do break).
The metal tongues of music boxes are similar to concertina reeds, but are plucked rather than blown. Tuning them is the same as a reed -- file tip or root. But yes, this is off topic.
