Судя по этому абзацу с вики, предположу, что Рафнек - это тот же Король Позругчик, только с использованием чисто баттлмеховских технологий, а не эрзаца :)
"During the massive expansion in production to recoup the horrendous losses suffered during the initial Clan Invasion of 3049, while for the most part Achernar focused on its existing lines for designs such as the Enforcer, Dervish and Locust, one lead designer suggested the radical idea of transforming the company's popular competitor to Sitwell Corporation's Powerman into a true BattleMech. Despite the Loader King's superb reputation for taking a beating, many balked at overhauling the design with BattleMech-grade components and only the belief of the lead designer, and if rumors are to be believed a spot of blackmail against Achernar's CEO, got the Roughneck into production."
