Picked up a 1972 Taylor barograph. This is a weather instrument with an
electronic rotating drum. On the drum is taped a chart and, in
combination with a "pen" (of sorts), barometric pressure is recorded.
After a week, the charts are removed and replaced with a fresh one.
I have one that records barometric pressure, temperature, and
humidity, and the drum is clockwork.
