VISUAL DESCRIPTION
The image is a black and white advertisement for the "P. B. Deviator, " a device intended to prevent trouble by acting as a preventive medium rather than as a curative measure. The ad emphasizes that the design of the P. B. Deviator renders it ideal for interpreting radial navigation aids such as those used for aerial navigation, due to its ability to average out random errors in these signals and provide more accurate navigational readings. At the center of the ad is an illustration of the P. B. Deviator, which appears to be a small mechanical instrument with dials and possibly some form of sighting mechanism or indicator. The text highlights how quickly this device can correct errors, mentioning an "instant" response where the yellow disc returns straight lines back on course if there's any deviation from a pre-set angle in level turns—presumably referring to aircraft piloting scenarios. It concludes by touting cost-effectiveness, stating that keeping this device operational does not require expensive maintenance or additional costs—it doesn't cost "a penny to maintain. " Below the main body of text are two logos—one stylized with "PB" inside what looks like an arrow pointing upwards (possibly symbolizing precision or upward movement), followed by another logo reading “DEVIATOR” beneath it—and contact information for P. B. Deviator Ltd. , located at Ulster Chambers, 168 Regent St. , London W1. Overall, this vintage advertisement reflects marketing strategies focused on reliability, ease-of-use, and affordability within aviation technology during its time period.
