There being two speed switches, that would make this a 4 speed then, wouldn't it?

The crazy thing is those resistance wires create heat when you are using the low speed. You can feel it come out of the housing, which is why there are tons of little holes. The singer version had a two speed switch in the handle.

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

Thank you for the nice post!

The Singer version of the vacuum with the speed switch in the handle will be coming up soon for a restore
