Description
This is an early oak barograph retailed by the Army & Navy Co-operative Stores in Westminster. Set into an Oak case with a lift-off all-glass lid, the movement has an interesting variation on the standard design. The linkage from the four central diaphragms would seem to be more direct and in line than common mechanisms of the period, possibly a novel innovation in an effort to reduce hysteresis or lag. Collins' book on Barographs features an identical instrument, also by A&Ncs (apart from the small knob on the pen arm lever which is very slightly different). This is quoted as being circa 1890 although my impression is that it's post Ww1, not least because the company plaque shows it has Limited Liability, a later business format. A selection of weekly charts, Sunday and Monday start, etc, a fresh bottle of recording ink included and a reprinted pamphlet by Negretti & Zambra Ltd describing operating instructions and guide to interpreting chart readings.
