The dewback seen in publicity stills from Star Wars Episode IV: A New Hope appears to carry four German M34 tornisters, similar to the one pictured above. One pack is mounted on the first strap encircling the dewback's belly, directly beneath the large, furry saddle horn. The second is placed behind the rider, on third (last) strap that encircles the dewback's belly. The third and fourth pack are placed similarly on the opposite side of the dewback. It is unconfirmed, but reference pictures indicate that the packs used on the dewback were early model tornisters which include leather shoulder straps. Later models simply had D-Hooks.
