If there are any experts or knowledgeable people on here on this item i would welcome your input.
When i was a kid and on visiting my uncles i used to play with this, when he passed away it ended up in my hands, all the kids that visited me also played with it. Its been stuck in the wardrobe for years and forgotten about, coming across it again and with the power of google i decided to see whats what. Unfortunately, its not complete, here's what I've found so far, its amazing what we all have lurking in cupboards that maybe not of value but are of interest. Below photos and findings so far.

Hi Bert1
Looks very interesting. As the article suggests it is like an old multi-function unit with the main purpose being to detect counterfeit banknotes, this would have been a very difficult thing to do in the 1800's.
I collect old scientific instruments but have not seen one of these before.

It would be an interesting hobby to have Kenmo, didn't realise until i started looking, some fantastic collections out there for scientific and medical artifacts.
