I have a spare player action rescued from the city dump 20 years ago.
There is no makers name on the spoolbox or anywhere except a small
stencil near a pneumatic stamped "roberts"; it doesn't look official
and appears to be the assembler.  The description of the pneumatic is
that there a block of wood attached to it and a port for the vacuum.
This unit is screwed on to the chest, two screws.  The tubing is lead
and the tracker system uses two fingers, one at each side of the paper.
I would like to know the make, and it would be available to anyone.
