I'm confused... are balusters the upper portion of the actual piston or the upper portion of the outer valve casing?
1. Upper portion of piston around the spring:
or 2. Upper portion of the outer valve casing:
I always considered the baluster to be the heavier top-section of the piston casing and the top of the piston assembly where the spring goes to be the cage... perhaps a hands-on techie can comment?
Solid wood balusters generally have a square block at the bottom and either a block at the top (block top) or a taper at the top (pin top). Balusters are generally made from 1-1/4" or 1-3/4" square hardwood. Standard lengths are from 31" to 43".
The baluster is indeed the upper part of the cylinder (upper valve casing). The part of the piston containing the spring and guide is called the spring barrel. This is the nomenclature that was used at the Schilke factory during my tenure there.
Originally it applied in masonry to a smooth double curved transition between two different diameters. Due to some similarity in appearance, the Greeks seem to have borrowed an Aramaic word balatz ("flower of the wild pomegranate").

So the balluster consists of the spring barrel, the spring, valve guides, alignment corks, valve stem, valve caps and...?

Mostly, in carpentry it refers to the filling uprights of a an open banister, a component of a stair railing.
In trumpet terms, the baluster is the top part (non-bearing) of the valve casing. Sometimes this is integral to the casing (i.e. one piece casing like Buescher, Jaeger and earlier Gezen, to name a few), but is is more common these days for the baluster to be a separate piece, hard soldered onto the casing. This gives the manufacturer the opportunity to use a different metal like rose brass or nickel silver for the baluster, whilst retaining yellow brass for the bearing portion.
