I don’t really know how to operate this guage but I have some background. It was invented by a catholic priest around 1912 or so and is used to predict the point of impact of a tropical storm. It does this by mapping the drop in barometric pressure to the guage with all the pointers on it. From there you’re on your own. Anyhow I’ve had it in my collection for years perhaps it is time to move it along. It is 25 1/4 inch wide by 15 tall and about 2 1/2 inches deep at the gauges.
