Today I posted two instruments to the collection website:

  • From 1941, an unknown aneroid barometer made in the former Soviet Union.  If anyone can identify a model number or location of manufacture, please contact me.  Go to Russian Barometer.
 
  • From 1951, a ML-436 US Army Signal Corps Assman Psychrometer, complete with a case of thermometers to fit it.  It was part of a AN/PMQ-1 Manual Meteorological Station.  Go to ML-436 Assman Psychrometer.
