A fellow technician just gave me the player stuff he got from another
technician's estate.  In it was a "... Descriptive Catalog of 'Style H'
Player Pianos", from the Hobart M Cable Co., copyrighted May 1917.

It appears to be a quite complete service/owners manual for the
Standard Pneumatic Player.  I have not seen one like it before.

If there is someone who is interested in reprinting this manual please
contact me and I will send you a photo copy to look at.  If you are
still interested I will send you the original.
