The polished brass & copper mark v dive helmet measures 10"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. 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.
