Vintage Hand Cranked Generator
No idea of the manufacturer or date on this one. Apart from the broken base it is also missing some other components.
However i placed a multimeter across the remaining wire and the slip ring on the armature and cranking the handle generates
a voltage. So with a little bit of work i think this can be restored.
Underneath all the grime was some nice shiny brass. A new base, brush and a few connections added and it's back in working order.
Some research on the internet revealed some other generators similar to this one.
They were used as demonstration equipment in schools like the one below.
