The Jawa was one of the first 12 figures released and saw a full production run right through to the final POTF cardbacks. Due to length the Jawa was in production is was inevitable that there were numerous variations both to the figure and the Blaster itself.
It's important to note that the Brazilian Glasslite line actually released the Jawa Blaster with the Princess Leia Organa figure in both Silver and Solid Black.
Note: The only Solid Black version of the Jawa Blaster was the Glasslite issue.
