Don Teach listed a number of firms that punch music rolls, which he
thought included all of the firms in the US.  I am sure there are a
number of others that punch music rolls.  Walter Moore has punched
rolls, and he has Carl Semon's dies for several different instruments.
I have punched rolls for over twenty years for organettes, Tanzbar,
Rolmonica, Play-a-Sax and other small instruments.
