R1-G4

R1-G4 was an R1-series astromech droid that was abandoned on Tatooine after it's owners were captured by an unknown group, possibly the Tusken Raiders. R1-G4 was eventually stolen by the Jawas, being placed aboard the Jawa Nebit's Sandcrawler. Aboard the Sandcrawler, R1-G4 was fixed and was in the lineup of droids that the Jawas brought to Owen Lars, never being sold. R1-G4's cold box had stolen transponder data.
