Over the weekend I was able to access and sort a box of valve parts from
Mike Kitner's estate.  There are about a dozen or so plastic valves of
experimental design.  These are clear plastic and seem to have neoprene
gaskets.  They are glued together and can not really be repaired.

Most of the unit valves in the box are wood, similar to Figure 21 of
Larry Givens' book, "Rebuilding the Player Piano," Fig. 21 and 24 look
like what these are trying to replace.  I am willing to send these
plastic "experiments" to any one who is willing to pay for the postage.
Otherwise they are going to the plastics recycle bin.

Most of the material in the box seems to be for standard stack type
valves that correspond to Figure 20 of Givens.  My 1994/95 "Durrell
Armstrong's Player Piano Company" catalogue shows on page 33 what many
of these parts might be.  There seems to be a lot of Schulz material
as well as some Autopiano.  There is probably enough material for three
or four pianos plus two pianos that would use the unit valves.  There
is also a set of retainers for the unit valves.  I can not really tell
one brand from another except by the catalog descriptions.

I am thinking that I may save the unit valves for my organ projects.
On the other hand, some of the findings and punchings for stacks I
would sell off at the 1994 PPCo price plus shipping, if the part number
can be matched in the original envelope.  Not that I want to compete
with Durrell, but there may be something discontinued that someone
needs to get a piano operational, and that is the whole point.

Also watch eBay.  I have some roll frames and such which will be going
to auction soon, in the next week or so, as soon as I can figure out
what category to place them in.
