Bought it unused fits a motor marine II. Thought it would work on my PT -30 housing and it won't. So I don't need it or can use it.will sell out right or trade for something I could use. Make offer have no clue on shipping cost. Retail on box says $368 B&H has them under $300 or better yet if you could turn me on to a adapter for the PT-30 housing I will pay a bird dog fee or send you some gear I don't need. I bought it cheap on ebay. Am in Dallas area.
