This is the ES-59. It is manufactured by (pulling out old star wars book) Kuat Drive Yards. It is used by many bounty hunters throughout the galaxy, but the most known commonly referred to is Joro Scallian the loner Geonosian found in a crater (will post more on him). This ship is highly recommended across the galaxy for its speed and twin hyperdrive combustion chambers.
Bounty hunters will often modify this model for personal gain.
Thanks for reading and keep bricking!
