Sanctuary, Henry Foss Proton Gun

original movie prop

As we see him in early first season episode Fata Morgana, the Sanctuary's resident tech guru Henry still needs to learn a few things about combat.  Quickly apprehended by invading Cabal mercenaries, Henry first drops his primary weapon and then proceeds to empty his pockets of various devices, including this retro-futuristic derringer-style pistol. Unnamed onscreen, this prop was labeled 'proton gun' as received from production.

Small static ray gun, of painted resin and other plastics, with transparent acrylic emitter fins.
