Leonardo Perretti's clock problem sounds fascinating.  I'd love to see
some of the very early church organs he has worked on.  It's hard for us
Americans (especially those of us who have never traveled in Europe) to
imagine having so many wonderful, OLD machines & buildings around to work
on and in.  I'm jealous!

Good luck on your restoration project, Leonardo.  I hope you find the
help you need.
