Han Solo carried this type of droid caller on his belt in Star Wars IV. In addition to summoning droids, these devices could also be used to restrain them.
This is an actual Kobold camera flash. Several different Kobold flash models were used to create the droid callers carried by different characters. Although some silver Kobold flashes were also painted black by the prop department, this model, which came in a black textured finish, is the correct model as carried by Solo.
