Operating Pressure of Tangley Calliope
By Bill Black

I would like to ask a question of Calliope fans.  I recently acquired
an unrestored Tangley model CA-43.  While examining my new treasure, I
noticed the following info on the manufacturer's name plate.

  Model CA-43  Pressure range 1/4 to 5/8 (psi, pounds per square inch)
  at blower speed of 700 rpm, tuned at 3/8 psi.

In looking at the Tangley Mike Kitner has, the following info is on his

  Model CA-43  Pressure range 5/8 to 1-1/4 (pounds)
  at blower speed of 745 rpm, tuned at 1-1/4

Both these machines were made about the same time because the serial
numbers are only 12 apart.

I'm wondering if the higher pressure model was intended to be louder
and the lower pressure model softer.  Would this suggest that they
tailored the machines to the intended use by the customer?  If anyone
who has one of these machines could take a look at their plate and
send me the pressure ranges at what rpm, I would appreciate it.  I'm
wondering if these were the only two variations (other than the theater
special which would have ST-43 on the plate).  Thanks.
