Ray-Gun 3: The Iron & Glass Corditizor

This heavy pistol utilizes plasma, supplied by an external top-mounted storage capsule, mixed with atmospheric oxygen and electricity from an internal D-cell battery to produce a super-charged blast of energy, vaporizing anything in it's range.
This weapon takes its cues from Steampunk design as much as old-school futurism.  I like all the bells and whistles.
