The original process was supposed to put a layer of something
other than aluminum on the inside of the cylinder walls... I
want to say silicon, but that can't be right...

But the process was producing blocks that cracked a lot. So
that's when they came up with the sleeving process. Too late
though for my '71, to which I'd taken an axe (Careful with that
Axe, Eugene...).
