What a fabulous working instrument! Set in in a polished mahogany case with a lovely lacquered movement, this extremely rare instrument has a two-weekly roratation clock creating a more condensed reading. Having seen only one other of these in 60 years I have had to have special charts printed therefore two years supply are available. 375mm wide x 197mm high x 215mm deep.
Exceptionally Rare 2 weekly Barograph
