11-7/8 IMPERIAL SYMPHONION DISC MUSIC BOX MOVEMENT. COMBS HAVE SOME SURFACE RUST. MOVEMENT NEEDS RESTORATION BUT IN GOOD SOLID ORIGINAL CONDITION. NO CASE, JUST THE MOVEMENT. 9 DISCS ARE INCLUDED IN VARIOUS CONDITIONS. ALL ARE CENTER DRIVE WHICH ARE CORRECT. SEVERAL ALSO HAVE EDGE DRIVE ALONG WITH THE CENTER DRIVE WHICH I BELIEVE WILL WORK.
