Can anyone help me with the size of the pneumatic for the glockenspiel
strikers on a Coinola piano: length, width, span.  I bought the metal
strikers from PPCo and I want them to swat pretty hard.  They will play
a Deagan 25-note glock from a theatre organ and be installed on a
calliope.

Another question: This glock has resonators.  Was it meant to be a
crystoglott (felt tip strikers)?  What would be the effect of removing
the resonators?  I don't want to loose volume, but I need the room.  I
have plenty of surplus vacuum.

Thanks
