This information comes from Mark Stikkelbroek in the Netherlands:
At Player-Care.com, I'm always looking for ways to help people by presenting information about player pianos. Sometimes I need a little help, and every so often I need a lot of help. Now, I need a lot of help. I'm creating a database of information about the Standard Player Action. Basically, the database will help people determine the age of "no-name" player pianos and player pianos about which very little is known. All I need is some simple, easy to find information.
