The easiest way to tell if you have a Single Valve or Double Valve Standard Player Action is to look at the space directly below the Spoolbox. The Spoolbox is mounted on a Deck Board which is about 5/8" thick. Between the Deck Board and the Stack, there is a 3" space. In that space there will be a piece of wood. If that piece of wood appears to be held in place by 7-8 small screws, you have a Single Valve action. A double valve action will have two
rows of screws that are spacing about 1-1/4" from each other that run the length of the upper section. Below is a picture of a Single Valve Standard Action. To Return to the Previous Page - Click Here I'll try to get some pictures to make this easier.... |
The first Lower Section pictured below has TWO Reservoirs. The one below that has only One.

Subject: Serial Numbers for Standard Player Action (by Diane DeTar)
I have several stack dates for action stacks made by Standard Pneumatic
Action Co. I'll just give you a few to help date the Auto-Art player
piano. These are verified dates from inside the stack as well as the
case number.
As you can see, there is a discrepancy with the chronological order as the 1924 number is smaller than the 1917. I started keeping track of the single- verses double-valve stacks and they indeed have a different numbering system, so I do believe that the single stack was made later and they started with another numbering system for that stack. The single stack numbers that I have are from 299698-403080. One other interesting fact is that the factory always stamped the bottom of the bellows with a completion date. If the bellows have not been rebuilt it would still be there and you can see it with a mirror and flashlight. It is right on the cloth where it is glued to the wood. |
Since "Player-Care" is an internet business, I prefer that we correspond via E-Mail (click here to fill out the 'Request Form'). However, if I'm not in the middle of some other activity, you can reach me at 732-840-8787. But please understand that during the hours from 8AM-5PM EST (Mon-Sat), I'm generally quite busy. So, I probably won't answer the phone. If you get the answering machine, please leave a detailed message stating the reason for your call. Also, repeat your name and phone number clearly and distinctly. By necessity, I prioritize everything in my life. And, if you call and just leave your name and number, and ask me to call you back, it might be a day or two before I return your call. Why? Because I don't know why you want me to call and I might not be prepared to assist you in an effective and efficient manner. If you leave me an E-Mail address (which I prefer), spell it out phonetically. The more you do to help me, the more I can help you in return. Don't rush. You have four minutes to record your message. |
