VISUAL DESCRIPTION
This is a vintage advertisement for "A New Weston Frequency Indicator, " which appears to be an electrical instrument designed for aircraft use. The image shows the front face of the frequency indicator, which has a circular dial with numerical values ranging from 35 to 45 in increments of one and smaller subdivisions between them. It features four mounting holes at each corner for secure installation. The text accompanying the image provides information about the product. It states that this Model 5193 is a new frequency indicator specially engineered for aircraft use, utilizing the ratiometer type and having a circular scale with an angle of 270 degrees and a length of 5 inches. This device is made to fit all standard aircraft voltages and reportedly indicates frequencies between 300 and 5000 cycles (Hertz). A key feature highlighted is its ability to provide readings independent of waveform or supply voltage variations, claiming accuracy within ±1% over most of the indicated frequency range. The instrument's immunity against external magnetic fields due to shielding against compass interference is also mentioned as an advantage. Additionally, it boasts self-contained construction packed in a standard bakelite aircraft case ready for panel mounting. Below this description, branding information emphasizes "Weston Aircraft Instruments" along with contact details for Sangamo Weston Limited located in Enfield Middlesex with telephone numbers provided alongside addresses in Glasgow (Scotland) and New York City (USA). Overall, this caption describes both the visual aspect of the advertised product as well as summarizing its purported technical specifications and advantages according to historical marketing materials.
