Antique SYMPHONION The Olympia MUSIC BOX 8Discs for Part Or Repair W/ 3 Discs. Here’s a nice little project. Discs are 8.25 diameter. Nice case, good bedplate and mechanism. Comb has all teeth. It’s a project that was started by my late father and never finished. Couldn’t find any examples that were the same size. Maybe it’s uncommon? Either way it’s a worthwhile project. Make me an offer.
