Hi,
You try to restore an instrument, but don't know how it looked like?
We are building a photoarchive with detailed-photos of grand-pianos for use in your workshop. You can also find some old patents there
You can upload your photos here, too. Your photos can help other restorers to make better work.
If you upload zips on our server, the photos will be published by the admins some hours later.
Everyone, who sends pictures will get a link to his website.
here`s the adress:

photoarchive for historic pianos

Thank you for having a look,

Stefan Schafft
piano technician, restorer
