There’s an auction going on Ebay at the moment for a one-of-a-kind hand painted HALO Army Nerf Firefly Rev-8 (modified from the thick plastic HALO Rev-8 LARP Plasma Cannon).
It’s been painted to look steampunk/antique using several coats of paint (clear coated).
This was originally a toy which takes 2 AA batteries and gives a flash of light inside the barrel when it quick-fires up to 8 Nerf darts (yes, it’s made to be played with LARP’ing peoples!). Check out this video on how to mod the toy:
