Photographer: R. C.
Caption: Cannon Elevation Mechanism
Additional Description: A simple threaded knob spliced by an elevating screw provided elevation. Contrast this to standard Army field pieces that used an elevating screw placed under the breech. Also note the lock piece lugs on the rear of the breech. In between the two "fingers" an arm was mounted a hammer. The hammer was pulled to the rear with a lanyard running beneath it. With a tug of the lanyard, the hammer rotated forward and fell upon a percussion primer cap that exploded under pressure.
