Description
Early trade brochure from the Penberthy Injector Company, Detroit, promoting both its water/steam-powered “Automatic Cellar Drainers” and the Model 33 automatic electric sump pump. A concise, display-worthy snapshot of the moment U.S. basements were transitioning from water-pressure ejectors to compact electric pumps.
• Penberthy brand-longtime maker of boiler injectors-selling domestic drainage gear to plumbers and builders
• Dating clues point to early-mid 1930s: “free from radio interference,” Oilite bearings, 110-V 60-cycle AC noted, “Model 33” motor-pump
• Illustrated pages with cutaways, specs, and printed list prices/capacities: Model S drainer $14.50; Model 33 pump $39.50; ring & split sump covers $8.50-$15.00; copper wire strainer $5.00; capacity table to 1,400 GPH at 1 ft head
• Uncommon subject for Penberthy (better known for steam injectors), appealing to plumbing/industrial ephemera, Detroit manufacturing, and early home-infrastructure collectors
