Let me correct myself.  One of my private emails stated that the
Tangley pipes would be voiced for a mere 1 PSI, or 27 inches of
air pressure, not steam.  I guess "high pressure" is a relative
term, but I suspect that the big circus jobs with the vertical
boilers were running a _lot_ more than 1 pound head of steam!

These Tangley pipes would be good for a modest air blower, though
they do require quite a big flow volume to make up for the "low"
pressure.
