Tony Greer's nostalgic post evoked some nostalgic memories of my own.
In the 1970s I bought several items from a firm in Lubbock, Texas, no
doubt the one he worked for, for a build-up "O" roll machine I built
here in Rochester, New York.  All of the items were beautifully done,
especially the roll frame, which never missed a beat or mistracked
playing the many "O" rolls I bought from Ray Siou (for 10 dollars
apiece!)

I also bought a multi-channel lock and cancel device, several drums,
a set of xylophone bars, and 25 reiterating pneumatics for the
xylophone.  Only these last, and the lock and cancel device, failed
with time.  I never cracked one open to see, but I suspect they may
have been built with Perflex pouches.  So the machine gradually fell
into disuse but I still have it and intend to rework it when health
permits now that I have retired.

Tony's post also brought back memories of visiting Ray Siou's marvelous
home and shop in Oakland during a San Francisco AMICA convention.  What
a legendary character he was!  Thanks for the memories, Tony!
