Hello,  A friend is in need of the unit which secures the pressure 
bar to the center spindle for a 19-5/8-inch Polyphon musical box.
He has the pressure bar but it appears this assembly was a pressure
fit and has vanished over the years.  If you can help with a part
or ideas to make a new one, please email me at <schmuck@wightman.ca>

Many thanks,
Ron Schmuck
