Offered is what I was TOLD is a WW2 vintage cast bronze plaque for US Navy Submarine Division One. It measures approximately 6″ in diameter and 3/8″ thick. There is one small spot (see arrow in photo) with very minor oxidation. It is fairly heavy weighing just under 3 lbs. I try to describe my items to the best of my knowledge, but I’m not perfect and could easily miss something.
