30's 40's Volt Meters

 Here are some examples of 30's/40's Voltage meters.
   The picture to the right shows a meter in a wooden case made by White elec Inst Co Ltd London and it also has 1935 printed on it possible the date!
   Well why have i got this in my house i brought this from Ebay too use with my electric chair that i made for Halloween.  I've added a light to the display so at the flick of a switch you see the needle shoot up unfortunately i'm not actually allowed too electrocute anyone.

This is a forties model made out of bakelite solid plastic last forever, not much info on this one but it weighs a ton wouldn't fancy carting this round in my tool case all day.

             My modern multimeter compared to the size of these two giant volt meters.
