1918 dated Springfield Model 1903 Mark 1 that has been converted to .410. This rare gun is the model that would accept the Pederson adapter (hence slot on the action for extraction of cases) It is very good all original condition with good markings to the action and barrel. It has been magazine restricted to comply with Section 2 rules. This means it is available on a Shotgun certificate. The mag plate has not been welded so will accept up to 3 rounds. Guaranteed not to see another one on the clay ground!
