Spotted on a table of old instruments while wandering around London’s Portobello Road market two Sundays ago.
(Click for a larger view.)
I found the labelling amusing.
Any idea what this might be?

My first instinct was that it is a telescope 🙂
Not sure about electric motor but looks interested for sure.

Hi SMQ – thanks for your comments! (I restored the original one from the spam bin once you mentioned it was there…. so people have the link.)
Cheers!

Looks like it’s a Barlow (or Barlow’s) Wheel: a simple kind of electric motor used mostly for demonstration purposes. The stellation of the wheel is just so that rotation can be easily observed; a simple disc would function as well.
