Hi Marc, It's a Standard Player Action, but you actually already knew that even though you didn't know it. :-)
In a way, it's a mixed blessing. A Standard is typically less expensive to rebuild than an AMPICO which is much more complex. Basically there are two types of Standard mechanisms. The single-valve action and the double-valve action. Some of the typical 'accessories' include push button LOUD, BASS SOFT and TREBLE SOFT. The economy models had lever controls which performed the same functions. All are manually operated.
It's relatively easy to determine the 'type' of mechanism. If you can see the front edge of the platform that the spoolbox is mounted on, it's a double-valve action and has 176 valves for the 88 notes. For the basic principal of operation of a valve, I invite you to see my webpage at http://www.concentric.net/~tuttleja/mybook.html.
