VISUAL DESCRIPTION
This is a vintage advertisement for "Smith's British Aviation Instrument Board, " which appears to be an early aviation instrument panel. The ad highlights the board's weight at 7½ lbs and mentions that the price is available upon application. Smith & Sons are presented as contractors to the British and Allied Governments, suggesting their products were used in military or government aircraft. The instrument board features several key gauges essential for flight: - Altitude Recorder: Allows pilots to set and record any required height with a button reset to zero. - Time of Trip Clock: An independent time recording on a subsidiary dial. - Revolution Indicator: Measures engine revolutions per minute (RPM) in hundreds. Additionally, there are other instruments mentioned that may not be visible on this particular board but are offered by the company: - Air Speed Indicator: Records airspeed as required by the pilot. - Clinometer for Longitudinal Adjustment: A tool used to measure angles of ascent or descent. - Clinometer for Lateral Adjustment: Used for measuring bank angles during turns. The advertisement also notes that two electric lights are fitted onto the board, likely for illumination of instruments during low-light conditions. Lastly, it states that they can quote customers for aeroplane accessories of every description, indicating a broader range of aviation-related products offered by S. Smith & Sons Ltd. , located at Speedometer House in London. The overall design and language suggest this advertisement dates back to the early days of aviation when such instrumentation was critical for navigation and control before modern electronic avionics became standard.
