This is a lovely 1920s barograph in good working condition. The polished mahogany case has a lift-off lid with bevelled glass and there is a chart drawer to the base. The movement has an eight stack of bellows and the brass movement is lacquered, the pen arm is of the pressure adjustment type - all typical of barographs produced in the 1920s. There is an original ink bottle and holder.
A quantity of weekly charts included in various styles, inches/millibars & Sunday/Monday start together with a fresh bottle of recording ink. I will also provide a reprinted copy of Negretti & Zambra's operating pamphlet with interpretations of barograph chart readings.
