Two late 19th /early 20th century 10 inch obturating plates for '9 Gun': stamped as per title to reverse with ribbed flange surrounding, 25cm diameter. *Notes - In the early stage of breech loading gun development an obturating plate was used by attaching a cannon ball to the plate by wires, the ribbing on the outer edge of the plate would match the rifling in the cannon and the plate would expand and seal the breech providing more projectile force. .
