Our National Piano plays very well, but the connecting rods on the pump
are made of pot metal and two of them have fractured.  Also, two of the
brackets or the wrist pins down on the pneumatics have also broken.
Pot metal again.  The first time a connecting rod and bracket failed,
it also split the pneumatic.

Before I investigate the possibility of having these parts reproduced,
I thought I would see whether by any chance there are replacement parts
available or what other National owners have done when these pot metal
parts fail.
