The kangaroo leather is a wonderful product for certain operations, but
it presents gluing problems on the hairside due to an unnaturally high
lanolin content.  In other words, it is very good for doing a box- style
pneumatic, but not so much so for a pouch.

Some people have had success by wiping the hairside with acetone and the
gluing with barge cement.  I guess I am too much of a "do it the way the
old boys did it" sort-of-guy to get involved in this.

I've never heard of it and wouldn't expect to. The production of 
leather, 
especially for pipe organs is most certainly a side product of the 
massive 
production of beef 
    


Actually it is a direct product of the huge industry dealing in
chrome-tanned cow, goat, kid, sheep and hair-sheep skins for the clothing
industry.  The US Government alone buys many thousands of dozens of skins
a month for use in military clothing.

In fact, it is because of the US government that we can get chrome-tanned
leather at all.  Chromium-oxide is a very hazardous and lethal substance,
and there is practically no way to dispose of the leftover salts.

So, the US Government (E.P.A.) merely fines the tanneries every year for
the illegal use and dumping, and the tanneries just work the cost of the
fines into the price of the leather!

I have decided that I choose to not think about this most of the time.

Whatever happened to importing naturally-tanned kangaroo leather from OZ?
The last I heard, it worked well, but it was difficult to find a reliable
supplier.
