Brass Chelsea Clock Used For USGS Stream Gauging Gifted To Me (c. 1920 (?))

A retired USGS hydrographer gifted me this clock, from an A-35 Freig Graphic Recorder he told me.
Vintage / historic instrumentation like this is such a – literally - solid reminder of the history of stream gauges and their measurements by the USGS across the USA, from the 1st measurement on the Rio Grande in 1889
It is a pleasure and indeed an honour to now have it on my office desk.
EDIT: Chelsea Clock tells me is a "water monitoring movements [they] made back in the [20s and] 30’s for customers like Stevens Water Monitoring in Oregon"
