This Short and Mason microbarograph dates from c.1925, numbered 1535/44.

The micro-barograph has a higher bank of aneroid chambers, which amplifies the movement of the pen on the graph-paper, overcoming the problems caused by friction of the standard barograph. They were therefore adopted by the Meteorological Office for more accurate readings.

This model has an all-glass lift off cover with no supporting frame, just chrome corner brackets, giving it a very clean look against the black base.

It has an brass "gilded" pressure movement upon which is mounted the 11-segment vaccuum chamber. The spring-driven drum rotates once a week, and is 7 inches tall, magnifying the trace by double when compared with a standard barograph. Papers are readily available. Indeed, it is sold with a plywood box containing a supply of papers, and also some flight weather records from 1964 for the Air Ministry Meteorological Office.
Overhauled and guaranteed for 3 years.
