Original GM manual antenna for 1957-1958 Oldsmobile, Buick, and Pontiac. Driver quality. The mast is fairly straight. Good rubber gasket and good plastic spacer. The chrome threaded nut is in poor shape and I can't remove it. Includes the coax and a broken lower mount. I've tested the antenna and it works fine. $125.00, includes safe insured U.S. shipping. PM me if interested.
