Aluminum, very good condition. 7" base plate, 8" top plate, 5" high, 1" forward. Will fit Northstar, Simrad, JRC and many other. Or you could bolt a plate on the top and mount anything to it. They retail for $200+ if you can find one as they now come without a top plate and you need to buy one. Anyway…$110 ALL fees and shipping in US included.
Post or PM.
