[Source] The E-3 blaster was a type of blaster weapon used for personal protection in the days of the Old Republic. Former smuggler Zeerid Korr carried one in an ankle holster in place of his ordinary twin BlasTech 4 blasters in the year 3653 BBY. He later carrried one on his farm on the planet Dantooine after he gave up smuggling, and had the blaster on him when a BT7 Thunderstrike arrived at his farm. Korr originally thought that it was the criminal organization the Exchange coming to kill him for not fulfilling his obligations to them, but it was in fact his friend Jedi Knight Aryn Leneer.
