Hello,  I am a French lover of mechanical music ... it is why my
English is not perfect !

I have a pneumatic piano named "le guillola" (manufacturer: A. Guillot
of Paris), No. 1 bis serial number 14128.  I restored all the mechanics
myself some years ago with the help of a fantastic man in Paris,
Douglas Heffer.  All is good now.

Now it is finished so I want to tune it.  My problem is that the A4 is
not 440 Hz but 415 Hz (near G#4), and I don't know if it is normal for
this kind of instrument.  Should I just tune it to this pitch, or it is
low because it was a lot of time without tuning?

Thanks a lot
