I found this Lantern on a fleamarked and got it realy cheap. It´s made of tinplate and the glas is a bottle. I think a cover on the spout is missing. In the stand is a battery compartment (2 C-cells - 3 V) and a switch and a small bulb is under the bottle. All in all it´s a good base to steampunk it.
Step 1: Changing the light
The wiring is from the original now, only the bulb was changed to the LEDs. Because the soldering was made for something completely different I covered the metal housing with tape down the hole to prevent any shortcuts or losses.
At this point the electric modifications will do it for now. Let´s do the steampunkination and look where it goes.
