[Source] Cassus Fett's Battle Armor was a personal suit of armor that had been designed for and worn by the Mandalorian warrior and tactician Cassus Fett prior to the Jedi Civil War. Fett presumably wore this armor at the Battle of Jaga's Cluster, when he killed the captain of a Republic frigate—an action that earned him infamy across the galaxy. After his apparent death, his armor was then acquired by the Rodian dealer and arms merchant Adum Larp, who placed it for sale at 15,000 credits.
