this is my first post.
I have an 1898 Bosendorfer 6ft (approx) grand, serial number 14930. Most surprisingly, it has a non-repeating Schwander action, serial 412752. As far as I have been able to discover, this looks like a Simplex D "spring & loop" design, which I understand was mainly fitted to small, cheaper grands. Actually, it has a "C" stamped at one end of the action rail (Simplex C??) My question is, would Bosendorfer have built it this way, or is the action a later modification? It all works quite well and reliably, though the touch is nothing special, as one would expect.
Perhaps Bosendorfer themselves might keep records?
Is it possible to fit a complete new roller action, and would it be prohibitively expensive..?
Thanks to anyone who might be able to help.
so it seems to be original. After what they did to his family in the 1914 war, Schwander refused to deal with Germans, but I don't know if that applied to Austria.
I tend to avoid using the word "Simplex" because it has so many different uses in and out of the piano trade, like the Simplex gears in cars, the Simplex upright action, and the one you mention which, as you say, is mainly found in cheap, average baby grands.
Perhaps Bosendorfers' website can help you.
I've emailed Bosendorfer to see what more (if anything) they can tell me about the piano.
You will see that the hammers are in dire need of replacement, but it actually plays quite well, with a nice full, warm tone, and it holds tune well.
I believe it is 190cm.
It is going to be replaced with a 1911 170cm Grotrian Steinweg whose restoration will be finished in a few months' time.
