According to the gent at the moving company, the organ has been there less than a year. He also says that it is in very good working order. I plan on going out to see/hear/play it next week. He is motivated to sell as he is coming into his busy season with moves and needs the storage space. He even told me he would "throw in a small organ and/or an upright piano if I would like." I thanked him, but unless he has a midi keyboard sitting around, I sure don't need another organ if I get that monster. As for pianos, well, I have my casio keyboard and with the Pianoteq software, I can play it and have it sound like a harpsichord or even a beautiful concert grand. That program is AWESOME. If you also like pianos, you should get the demo version. It is available at http://www.pianoteq.com.
I tell you, I am like a kid in a candy store. Since you were kind enough to provide me with the model number of the Commodore, I did further research and found a guy in the states who has owner's and service manuals for almost all the Hammond models. I even found 2 guys who both have this model (with the ebony/walnut/chrome) and one told the other how to fix his when some of the keys stopped working...including cleaning the contacts with a special solvent and even using a standard-type eraser if the corrosion isn't too bad.
So, I'm hoping to get 3 boards to insert that will allow each manual and the pedal board to adapt to midi. So I don't think I could be happier.
And, since reading how many on here get to practice an hour a week in local churches, I'm thinking of asking some of the churches in our neighborhood if I might be able to do the same. There are some grand old churches that I'm quite sure have some fabulous organs in them.
On another point, are you familiar with a Danish organist by the name of Carlo Curly? Or maybe it's Carlo Conti (getting old, you know). He used to be very good friends of a couple of my friends when I lived in Atlanta about 15 years ago. He would visit for a month every year. He gave "private" concerts in a few churches for a close group of friends...they'd all go in at night with bottles of wine and he would just lose himself at the keyboards.
Unfortunately, I was never privy to those, but I have heard him play on records (see, an oldie) and he would also play their grand piano at their house. It was quite a privilege.
