These machines were manufactured circa 1880 and were marketed by J. Woodward & Sons. The device is screwed into the ground, the angle set, the spring wound, a target is placed on the fork and when the shooter calls "PULL" the string is pulled and the target spins off into the air. Some sources indicate the targets can fly 150 yards. The targets are made of sheet metal and can be bent to change their flight path. Comes with a winding handle, pull string, extra spring, wooden case and 98 original targets.
