I'm a mariner and these barometers where standard equipment on Russian ships in the Soviet Era I was Captain of the former soviet drillship "Muravlenko" and it had one of these.

It could be earlier as the design has not changed much since introduction
The instrument reads in mb and centigrade and mm/Hg
