This is the Ryobi casting reel "Cast Pro V-MAG4," released in 1983. It was released as a baitcasting reel equipped with electromagnetic induction brakes (magnetic brakes), following Daiwa's Phantom Magforce. It's a model that converted the Cast Pro 400V to magnetic brakes, and its weight is 237g. The standard retail price was 7,400 yen. It features a sturdy aluminum die-cast integrated frame, which is said to have had little frame distortion or play. It comes in its original box with line attached, so I will ship it as is. Please understand that I don't know if it works! Feel free to comment if you have any questions.
