SOPP301: Do organ builders have online database with specs on every instrument they’ve built?

This question was sent by Dan, and he writes: Hi Vidas, back in June, i’d tried out a small casavant organ, in a place which is used for people to stay at, they do corporate events there, and other stuff, and the owner of the place, doesn’t really play the organ. She wants me to play it on a couple dates in november. It’s a 1929 Casavant organ, and it’s their opus 1375. ​When I’d tried the instrument, I was mainly using the crescendo pedal to control it. Those can give you sometimes less than desirable results. I’d asked her if she could provide me with a stop list for the organ, so I could know what it has on it, so I can have finer control over the instrument. Her response was that she doesn’t play the organ, and that we’d have to get somebody in to help. Does Casavant, or any other organ builder for that matter, have an online database with specs on every instrument they’ve built that I could access? OR would it be worth contacting Casavant about this? Secondly, the instrument hasn’t been looked at as far as tuning and maintenance for at least a year or two, and they don’t seem to have a regular contract with an organ technician. I suggested that they at least get one in, to tune the instrument, as when I’d tried it, it really needed it in my opinion. Any advice in this situation would be appreciated. Thanks. Dan
