Vintage Dexter Model 20-E 'Double Tub' Electric Washing Machine

This is a vintage dual-basin electric washing machine, commonly referred to as a 'Double Tub' model, manufactured by The Dexter Company of Fairfield, Iowa, likely dating from the 1920s to early 1930s. The unit features two large cylindrical basins constructed from copper, which have developed a heavy, characteristic green verdigris patina along with visible surface oxidation and rust on the supporting iron framework. The main wash tub is larger and equipped with a galvanized metal lid, while the smaller second tub served as a dedicated rinse basin or spinner zone. The machine is supported by a heavy-duty wrought iron or steel frame with integrated casters for mobility. A unique feature of this model is the integrated mechanical arm and wringer mount assembly at the top, though the rollers for the wringer appear to be missing. Notable condition issues include significant rust on the lower structural supports, motor housing, and drainage pipes, as well as pitting on the galvanized lids. The copper interiors show typical wear for their age, with some denting visible. These machines were hallmarks of early domestic automation, utilizing a single motor to drive multiple components via a series of gears and belts located beneath the tubs. This piece represents a transition in laundry technology from hand-cranked tubs to fully mechanized household appliances.

Based on my visual examination of the Dexter Model 20-E 'Double Tub' washing machine, I find it to be a genuine representative of early 20th-century industrial domestic engineering. The authenticity is supported by the specific casting of the iron frame, the characteristic copper basins, and the identifying nomenclature of The Dexter Company. The condition is 'as-found' or 'relic' grade. While the copper tubs have preserved well with a desirable aged patina, the significant ferrous oxidation on the undercarriage and motor housing, combined with the missing wringer rollers, negatively impacts the value for functional collectors. However, for the industrial decor market, this patina is often seen as a virtue. Currently, the market for early electric appliances is stable but niche. Comparable sales of dual-tub Dexter models in similar unrestored condition typically range from $400 to $700. The rarity of the 20-E is moderate; while many were produced, few survive with both copper tubs intact. The primary value drivers here are the aesthetic appeal of the copper and the completeness of the mechanical drivetrain. My assessment is limited by the inability to inspect the motor's internal windings, the lead content of any solder repairs, or the structural integrity of the oxidized iron frame. A physical inspection would be required to verify if the motor is seized and to ensure no hairline fractures exist in the cast-iron gears. To fully authenticate the manufacturing date, I would need to cross-reference the serial number on the motor plate with the Fairfield, Iowa factory records.
