Hi All,  By chance does anyone have a manual for a Model "A" Pratt-Read
player action?  Don Teach sent me a picture of a 1917 Pratt-Read
tracking device, which I now know was used in the Model "A".  He also
sent a drawing of a Pratt-Read stack, which also appears to be from a
Model "A".

A young man in California recently sent me a number of photographs of
the Model A Pratt-Read action and he's hoping I can find some technical
information to help him connect up some devices that were either
bypassed or purposely left disconnected.  I feel certain I could figure
the system out if I could see it close up, but I'm 3000 miles away...  ;-) 
Thanks in advance for any help.

Musically,
John A Tuttle
