Description: This is apparently a less expensive model which
retains many features of the more expensive models. It has a
wind-vane speed regulator, instead of the more complex Foucault-
style; it has a self-contained gear system for moving the
recording brushes up the paper to provide extended recording; it
has a weight motor, instead of a spring motor; and it is shown
with two recording brushes. The image, however, shows that this
is not a Zimmermann device, since name of the firm F. Wagener,
Berlin can be seen at the upper right edge of the table on which
the device stands. (Expanded caption Copyright 1998, Edward J.
