This is a 1953 Genco Sky Gunner arcade game. These were played by most all the guys from the early 40's until the advent of the video game. These are electro/mechanical and are relatively simple in concept and are rare to find in full operating condition. They are also very addictive! A real trip back in time. We must charge extra for playing this as they are very expensive!
Looking inside the target viewfinder. You have 300 shots and if you get over 250 hits you get another 300 shots! The targets explode, and the machine gun vibrates and makes machine gun sounds and a bell rings when you make a hit.
