Any time you get wine-colored motor cloth, beware -- it came from PPCo.
Durrell sells supplies to Schaff and most of the other piano suppliers.
It may be older than Durrell's [current supply], however.  That may
make it from a better batch, or it may just really be old.

When you recover any pneumatic, do not trust anything.  Blow into it
and make sure it is totally airtight, _everytime_.  The key to good
restoration is test, test, test constantly.

I suggest you purchase only the cloth from Felix Trading in Australia.
Organ Supply Industries (OSI) sells the largest selection of their
cloths and leathers.  Schaff also sells some of it.  Always specify
Australian cloth or you might get Durrell's.  Felix will not sell to
you [directly] because of contractual arrangements with Schaff and OSI.

Write to Organ Supply Industries on your company letterhead and ask for
their rubber cloth and leather sample card.  They have a large catalog
in ring binder form.  They may charge for it without an order.  Specify
that you are interested in the products from Felix Trading that they
sell.  They also have twill hose, or they did the last time I ordered.
