Today I added a 6 page catalog excerpt for the Kollsman altimeter setting barometer that was already on the website in the instrument collection.

​See Kollsman catalog.

I also added a 1939 catalog of R Fuess thermographs and hygrothermographs to the R Fuess catalog page.  It is 20 pages long.

​See R Fuess catalog page.

I also added a catalog web page for the US weather instrument supplier Verichron.  They supplied home and decorative weather instruments during the 1960s-1980s.
