Today I added two more excerpts from a Russian language catalog:

• ​Fritz Lange-Optik - a short catalog section showing hygrometers.  Go to Fritz Lange-Optik Web Page.
• Paul Wegener - a short catalog excerpt showing psychrometric devices.  Go to Paul Wegener Web Page.

Today I posted new web pages for three more instrument manufacturers that operated in East Germany.  The catalog excerpts are from a Russian language catalog.  The catalog is undated - I think it's from 1958-1972.  This includes:

• Arnold Fliedner in Ilmenau.  The catalog pages show mercury barometers made by Fliedner. Go to Arnold Fliedner Web Page.
• Glaswerke Ilmenau. The catalog pages show mercury barometers made by Glaswerke Ilmenau.  Go to Glaswerke Ilmenau Web Page.
• Roessel-Messtechnik in Dresden.  The catalog pages show recording instruments made by Roessel.  Go to Roessel-Messtechnik Web Page.

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.
