thanks ,Ben and Tom ! it is interesting that at that time we distribute vacuum cleaners (trophy) to reward the best sellers ! but that was another time !
this vacuum cleaner cannot have been manufactured in 1929 ! ROYAL introduced its new Royal Purifier model to the market in 1929

Tom ! your Hoover senior is a beast !! this huge motor and this big copper plate 😮 I would love to see it working ! I corrected the DC with a bridge rectifier to run a very old GE electric fan (DC motors are extremely rare)
Thanks for the photo Tom 😊 so no speed variator like today but an electric resistance like for my old electric fans ! energy consumption remains the same at low and high power and the resistor gives off a lot of heat
