Mad Scientist Lamp

This is my mad scientist lamp. I used a voltmeter from an old aircraft, its probably been high up in the sky with the air kraken and zeppelins! It has no glass though, it was broken at some point, maybe when the plane crashed after a raging battle with sky pirates.
I aged the wood myself and the bulbs used are genuinely old, I got them from my aunt Edith who is 100 years old! I hunted down some brass nails for the box and round the back there are 2 little copper clasps for the back pannel which comes off so I can repair it if it breaks.
