Fictional tool for shooting the rope pins into the ice and used later by Lex to shoot the back off and Aliens head. This was from the original Propstore sales promoting the film. I know of two made, this is static with no function or belt, it is mostly fibreglass. The hero was donated at the time to Planet Hollywood.
At Shepperton Studios Steve Howarth built the model from drawing plans and production cast from that.
