Today I posted excerpts from a Russian language catalog showing meteorological instruments from three manufacturers in former East Germany.  The catalog is undated but I believe it is from 1958-1972.  These included:

• Fischer - The excerpt was added to the existing Fischer Catalog Page.
• Foerster - Go to the new Foerster Catalog Page.
• Junkalor - Go to the new Junkalor Catalog Page.
