Accessories include the belt, ammo pouches, and the bandolier.
You could also make your own Jawa blaster, but I cannot help with that. Sorry.
For the belt and ammo pouches, you may simply use any wide leather belt (length 30-44 inches).
Slide the belt through the loops on the back of the ammo pouches. I used two pouches (one on the front, one on the back).
Here is a picture of the belt, pouches and bandolier.
