The Electro Shot Shooting Gallery made by Marx Games was a noisier version of the Magic Shot Shooting Gallery and had an electric machine gun instead of a pistol.
The idea was the same though - you had to fire at a series of fairground-style targets such as a clown head, a lion head, bells and spinning things using the little metal pellets.
The machine gun was electrically powered and had a small motor which would noisily fire lots of pellets at the noisy targets and pellets that missed would noisily bounce off the plastic screens. Because of the noise, most children were banned from using the toy when the TV was on!
Did I mention that the Electro Shot Shooting Gallery was also quite noisy?
