I have leather on the bellows of my reed organ from 1881.  It's a small
"cottage organ" with 5 stops, by Estey.  It's in very good condition,
except I'd like to replace the bellows as an initial step towards
restorations.

My uncle said that leather may be revived by oils, and that it can be
worked into shape again, thus being no longer porous.  I don't want to
invest in new leather for the bellows, and I'm not going to use
"bellows cloth" if it was originally leather.

Is there a way to salvage old leather?
