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?

Looks like it’s a Barlow Wheel: an early electric motor.
(seems my original comment is stuck in the spam queue due to a Wikipedia link…)
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.
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.)
Not sure about electric motor but looks interested for sure.
My first instinct was that it is a telescope 🙂
