There is a woman in Colorado who transcribes the various Pitman varieties, but she's not cheap. You can find her by Googling Dorothy Roberts Pitman Shorthand.
Alternately, the gentleman who runs The Joy of Pitman Shorthand might be able to transcribe, or knows somebody who can. Fortunately, the sample is in excellent condition.
If you are able to get this deciphered, it would be interesting to hear what it says.
