This is an action toy, with some die-cast metal parts, of a science fiction/anime character or item.
Aoshima brings us this very excellent finished die-cast model of the Type 66 Maser Cannon, first seen in the Toho film "War of the Gargantuas"! The detail is dead-on, and it even lights up! Not only does it light up, but the Maser charger in the "neck" pulses linearly, just like in the movie. (Headlights do not light up, however.) Requires two AA batteries, not included. It's a pretty big piece of hardware in 1/48 scale, too--35.6cm long, or just over 14 inches!
