An 87-page reference book designed to aid buyers of Pianos, Player-Pianos, and Reproducing Pianos in selecting an instrument. The reference is broken down into Three Parts. I. Instruments of Established Name and Character. II. Instruments bearing Special Names or Trade Marks. III. Manufacturers of Piano and Player Pianos. "All preceded by Chapters on Piano Building and Buying designed for the guidance of prospective purchasers." The work covers how pianos are graded, how to buy an instrument, and how to care for the instrument. The importance of this reference lies in the fact that it gives detailed characteristics of more than 100 of the top name pianos ever manufactured. And considering that there have been more than 10,000 piano companies, knowing which ones are in the Top 100 can be very valuable when deciding where to spend your money.

Produced in 1917, this 36-page reference has the finest gray-scale graphics I've ever had the pleasure to view. They are so good that I decided NOT to have the reference printed on paper. Instead, each page was scanned at a resolution of 150 DPI and a variety of electronic files were produced. This reference is ONLY available on a CD that I produced. It contains all of the original scanned files as well as an Adobe Acrobat (.pdf) file and a huge Word Perfect (.wpd) file. The beauty of these program files is that each page can be magnified to over 200% without losing the clarity of the graphics, making it possible to easily see details that are often difficult to see with the naked eye in the original paper manual. Also, through the magic of 'image mapping', you can access super-high resolution images by clicking on any image inside a web page. These images were scanned at 300 DPI, and they are twice as clear as the images in the individual pages. All files can also be accessed individually in 'My Computer'. Or the pages can be viewed as web pages.The CD is designed to automatically open your default web browser when the CD is put into your CD Drive. Lastly, if the web browser is connected to the Internet, you can also access everything at Player-Care from the links on the main default web page. S/H within the US is $6.70.

Strauch Bros. Pneumatic Player Actions manual. Very detailed explanations of all pneumatic components with accompanying graphics. Originally printed in 1925. Excellent illustrated parts breakdown section showing every single part in the entire player mechanism and piano actions (grand and upright). Very interesting pictures of workers performing various tasks inside the factory add an interesting touch to this manual. This is a "How it Works" manual and not a "How to Fix It" treatise.

Made during the 1960's and 1970's, the 'Universal', which was made in California, was the first player piano to use synthetic 'Perflex' pouches. Also, it was the first player piano to have an all-aluminum stack with rubber gaskets and neoprene valve facings. Thought not to exist, an original service manual was recently located. To it has been added the electronic schematics discovered by an engineer at Story & Clark, making this the most complete manual available for this player system. Complete with a short Troubleshooting section and Illustrated Parts Breakdown. It does not contain information about the Theory of Operation or Rebuilding. 8-1/2" x 11", 20 pages.

This Universal Service Manual was copyrighted in 2009 by Bob Stanoszek. It contains Six Sections that cover Rebuilding, Supplies, Adjustments, Service, Tubing, and the 'Classic' version of the player mechanism. While a majority of the information came from the original Universal and Classic service manuals, this manual also covers a number of the more common problems found in the two systems. The reference also has comprehensive listings of all of the parts and where they can be purchased. This reference is now part of my personal technical library.

Tubing schematic for both the upright and the grand. This is the "Licensee" version-the most common type of Welte-Mignon. Can be distinguished from other reproducing pianos by the tracker bar: All openings are the same size and have a pair of staggered tracking holes to read the edges of the music roll. Aside from these 'tracking' holes, the regular line of ports will total 98. (3 pgs - 8-1/2" x 11" glossy)

Upright and Grand. 24 pages. Different from the Kohler & Campbell built "Licensee" by Autopiano. This player action uses the standard 11-1/4" wide Welte-Mignon music roll, but construction of the mechanism was different and was built in Poughkeepsie, NY. To distinguish from the Licensee version-it should have a chain pulling over a roller on one of the expression pneumatics.
