What about if we go about finding out the number, location and model of the pianos we know about. Sounds massive and probably it is already being done.I suppose a tunners and the sellers would have a specially good vantage point to know these things.Cheers,IU
Sure.there is a finite number of pianos that have been made. Each of those pianos either has survived and is somewhere, or has been destroyed.For the ones that have survived, where are they?This is a good start:https://www.pianostreet.com/smf/index.php/topic,2741.0.html
I'm thinking Google Earth. Virtual fly around looking for pianos.
