VISUAL DESCRIPTION
This is a vintage advertisement for the Smiths Sensitive Airspeed Indicator, an instrument designed for aircraft. The ad emphasizes the ease of reading, accuracy, and lightness of this new aviation instrument from Smiths. It features separate scales for two pointers that make readings quick and unambiguous with each division on the outer scale representing 2 m. p. h. , or knots. The ad claims remarkable accuracy throughout its range and notes that it's already in use on high-speed military aircraft. The airspeed indicator itself is prominently displayed at the bottom of the image; it has a classic analog dial design with markings from 0 to 500 units (presumably knots or miles per hour). Available case sizes are mentioned to fit international standard dimensions in ranges from 50-300 knots and 50-600 m. p. h. Smiths Aircraft Instruments Limited promotes their comprehensive technical service backed by unique manufacturing facilities and invites collaboration with industry worldwide to solve instrument needs and problems. Below the text, there's a stylized illustration depicting what appears to be an early jet fighter flying above clouds with searchlights scanning the skies—a nod to contemporary advances in aviation technology during that era. The company details at the bottom indicate "SMITHS AIRCRAFT INSTRUMENTS LIMITED" located in Cheltenham & London S. W. I. , suggesting British origins for these instruments.
