The weapons on Lost in Space were always very appealing. Being alone in outer space with so many unknowns and potential threats make weapons a very critical part of any space adventure. We are all familiar with the cyclops monster scenes in the early episodes of Lost in Space. In these scenes we see Will Robinson firing a first season laser pistol at the giant cyclops monster and later we see Major West firing a laser rifle at another cyclops. Lost in Space weapon props are highly sought after collectibles but unfortunately there are a lot of replicas out there deemed to be authentic but are not. Genuine weapon props will cost thousands of dollars and be very hard to find.
