The Marksman repeater was a classic slingshot that was sold somewhere from the 70's to the 90's. It was completely molded from plastic and had an ammo storage that released a steel ball when the button on the front was pressed. The slingshot had a little sight on the right fork, and was built to be supported by fingers, an important feature that most of today's slingshots are missing.
This large extended-fork slingshot was once made by Marksman. It shares handle and Wristbrace with the model 3040, but has a very long fork, made of stronger steel than today's marksman forks. The original bands were tubular, similar to those used on the 3040.
