Today I added a Negretti & Zambra M2236 Typ2 aneroid barometer to the website.  I believe it was made in 1979.  It is unique in that it has an odometer-type digital display to indicate the pressure.  A knob on the barometer is turned until an indicator light changes, at which time the digital display indicates the pressure.  It obtains power from one 1.5 volt D cell battery.  The instruction booklet is available for download.  I found it in Germany.  It works well.

I also added a second Safonovsky Gidrometpribor BAMM-1 barometer to the website.  This one was made in 1989 and works well.  It seems to have a more robust pressure mechanism than the non-functional 1978 BAMM-1 that was already on the website.  I found it in Montreal.
