The Cat's Meat Shop".
Whilst obviously a tongue in cheek satirical cartoon lifted from the pages of a late nineteenth century edition of Punch magazine, there are none the less certain elements which have in some way been adopted by the current force. Ok, riot shields are slightly more robust than a wicker basket lid but the principle remains the same. Quarter staff's and baton's are essentially the same and the rattle on the helmet presumably works in the same way as a siren on a car - ie. "Get out of the way, I'm coming through...!".
But the most striking element in mind is the inclusion of a battery pack and, at point K., "electric wires up sleeve to shock opponent". So maybe in the same way that Leonardo da Vinci is credited with conceptualising the first helicopter design, perhaps the Taser stun gun was designed by a Victorian visionary?
