One toy that was very interesting was the “Mighty Mo Cannon”; this was purchased from a flea market. It was used and it only had one canon ball with it. I do not recall it how the cannon operated but I do remember how much fun it was to shoot that cannon ball from it. I searched every garage sale and flea market for other cannon balls but never found any more.
This cannon was from 1963 and it measured 27" long. It needed no batteries. It featured a breech loading & spring action remote control firing. To operate you had to open the breech door, remove cartridge and place cannon ball on rod, push down with plunger. Load the cartridge into breech (there is a tab that matches the slot), Close the door. Cannon is ready to fire by remote control or manually. The spring action remote is held on by two screws, one on each side, if that is broken the cannon can still be fired by pressing the button. Cannon can also be elevated or lowered in different positions.
