An industrial mid-20th-century vintage "Speedy" moisture tester, manufactured by Thomas Ashworth & Co. Ltd. in Burnley, Lancashire, England. Designed to measure the percentage of wet weight using calcium carbide pressure reaction, this heavy-duty cast aluminum pressure vessel features a robust stirrup clamp with a top T-bar screw handle and a stamped serial number (48868) on the shoulder. The base houses an inset pressure gauge calibrated to read "Percentage of Wet Weight" from 0 to 20%, making it an iconic piece of industrial engineering and scientific heritage. Good vintage condition consistent with age and field use. The cast aluminum vessel retains a soft, age-related patina with minor surface scratches, tiny oxidation spots, and light wear to the metal. The threaded T-bar clamp turns smoothly, and the rubber seal appears intact. The inset gauge dial under glass remains clear and fully legible with light wear to the black painted rim bezel. Mechanical functions are unverified for operational precision. Dimensions: 27 cm (H)
