More Instruments

Today I posted 5 more instruments in the collection section of the website.  These included:

1. A Julien P Friez & Sons barograph from the 1910s or 1920s that was used by the US Coast & Geodetic Survey.
2. A Yanagi Type 6 marine barometer from 1983.
3. A Fischer Type 103 marine barometer.
4. A GMS barometer that was reportedly used by the Soviet air force.
5. A Henry J Green, US Weather Bureau pattern, Type 103 mercury maximum thermometer.

I hope to post a few more instruments in the next several days.
