I am rebuilding a Polyphon 15.5-inch disc music box. It is a single
comb mechanism, with the comb in front of the star wheel gantry. It
is presenting two puzzles which may have a related answer. Most of you
fellow MMD'ers have lots more experience with these than I do, so here
goes. (Attached is a photo which will help explain.)
Dampers: There are no dampers present. There is a small rail of star
wheel brakes located on the gantry opposite the comb, but no dampers
and not much room to put any dampers on the comb side of the gantry.
The "Disc Musical Box Handbook" shows a slot cut in the bedplate to
make room for dampers on this type of comb, but no slot is present.
Any ideas or advice?
Extra Comb Holes: There are two slotted holes in the top of the comb
and two holes in the side of the comb block. Could these be for a
damper mount, or for a zither? The photo shows the holes clearly.
If anyone could e-mail back to me a photo of whatever attaches here
looks like, I would really appreciate it, because I would like to make
it work as much like it did originally as possible.
Thank you very much,
G. W. Finger
