Product Overview

After firing a canon, the most difficult task was to repeat the shot by setting the gun back in the original firing position. Accuracy upon a military target was crucial and saved lives. This device was a way to correct for recoil and place the shot on the original target - There is a border around the image. Image size is correct. Many sizes available.
