One of the exhibits in the planing stage right now will be called "Light Artillery" and will feature this type of trench art.
I love stuff like this.
20mm is probably the smallest I've seen with a full size light bulb. It looks like a 75mm base?

Sorry I'm more in it for the aesthetics than the actual components!
"Honestly, I'm not sure, except for the .45 ACP cartridges around the bottom (whcih are all WW2 dated - I checked when wiping it down and putting in new electrical guts). I THINK it's a 105mm US artillery case cut down for the base with a 40mm cartridge for the shaft (!). You could measure the width of the projectile on the shaft to confirm the width..."
