I have now examined the cloth further and would like to adjust my
obervations  in the previous letter a little. The little leakage that
is, seems to come through the porous wood in the pneumatic leaves. I
was just very surprized that the cloth had such a dry and brittle
surface. I have however added some silicone spray to the outside of
some bellows, and then the rubber turns soft and black as it should be.
The cloth now also seems to crease more evenly instead of being
"broken" in the folds possibly making holes in the rubber.

(Do not add silicone  INSIDE the pneumatic channels, or on anything
else inside, or on leaky old bellows, the silicone will make dust clog
to anything  inside. Leaky old bellows are also too late to preserve...)

Since the pneumatics  now are looking  OK I would not like to bother
Player Piano where I bought the cloth, by a complaint on something that
was easily fixed by me.  Their business is running on low resources due
to not so fortunate business the last years. It is in everyones
interest that they survive. I will suggest that it is best to be
forgiveable if something from them maybe have been stored a little too
long, but still can be preserved  (eg. mink oil for leather) The
pouches, and valve leather and everything else that I bought for the
restoration looked excellent, and it were similar in colour and making,
about 70 years after the original production of the piano!

You are lucky to have your WIFE help you with the "tricky handwork",
everyone else have to do everything themselves. ;-)
