The deluxe polished brass & copper mark v dive helmet measures 18"H. Not only is it a incredible display item but is a pleasant reminder of when we began to explore the depths of our vast oceans many years ago. The base in the picture is sold separately. It will add a definite nautical touch to whatever room it is placed in and is a must have for those who appreciate high quality nautical decor. It makes a great gift, impressive decoration & will be admired by all those who love the sea.
