Edwardian Mahogany Barograph

This is an Edwardian mahogany cased barograph in that typical style manufactured during the first quarter of the 20th century. It has bevelled glass all round and there is a chart drawer to the base together with a lovely original cut-glass ink bottle. A small blank brass presentation is available if required. A quantity of charts and a fresh bottle of recording ink will be included. There is also a reprinted copy of a period instruction pamphlet showing setting methods and how to interpret typical chart recordings.
