Garrett P. Serviss' Prop Martian Gun

Origin
Garrett Putnam Serviss (1851 - 1929) was an American astronomer, made astronomy popular and an early science fiction writer. Although gaining a law degree at Columbia University he never pursued becoming an attorney. Instead he started his writing career in 1876. Serviss' favorite topic was astronomy and of the fifteen books he wrote, eight are devoted to it. He was unquestionably the most read author on that topic that anyone prior to his time. In one of his most controversial stories, Edison's Conquest of Mars, mankind launches an attack on the Martians' home planet and one weapon the Martians use are specific ray guns, one which Serviss' sun made a model of. The reason so much anger surrounded the prop was because the original story, Fighters from Mars, was an unauthorized and heavily altered version of H.G. Well's The War of the Worlds
