A friend of mine has an O-roll built-up orchestrion that was made with
a stack using modern-made parts.  They have all failed, evidently from
stiffened pouches that can't be replaced.  The piano is a Haddorff,
serial number: 63185, made circa 1915.  The scale is 1/2-inch.  Does
anybody know what kind of stack it originally had?  PPCo lists three
used in this brand.  I'd like to get a rebuildable stack that will fit.
