Here's a stretch!  I have an inquiry from a non-Internet friend living
400 miles away.  He has a musical instrument museum and is having
problems with a Roenisch Hupfeld Clariona upright piano.  Problem seems
to be, how to get wind (or vacuum) to the stack.  If anyone can help or
has experience rebuilding one of these, please contact me and I will do
my best to pass on the information.  Meanwhile I'm trying to persuade
him to get Internet literate.
