Today I added a Naudet marine barometer to the website.  I call it a marine barometer because I bought it from the ship breakers in India, it might actually be a laboratory barometer, it has no means of wall mounting.  I suspect it dates from the 1980s.

See Naudet marine barometer.

I also added a 1903 Eimer & Amend catalog excerpt to the catalog collection on the website.  It contains a few thermometers, hygrometers, and a syphon barometer.

See Eimer & Amend catalog page.
