I like the two test lamps in series, and especially that rotary commutator sign flasher.
Ooooh yes, that one's a real classic!
At my former school (graduated in September) students of the full 5 year course (technical High school, I did the 2 year college) still learn to rewind and repair small appliance motors and similar stuff. All students. teachers and so on can take their stuff there to have it fixed for free.

An important job of the electrical worker is repairing toasters! Another era, for sure.
Yep, $9.95 throw-away toasters from China. Who'd have thunk it back then?
Thats really cool! I want to see one of those sign flashers.
Reminds me of the ringing machines in old telephone exchanges. They operated on the same principle with a motor driven cam assembly to produce all the appropriate flashing signals and tone interruptions.
