This from the 501st Tusken CRL:
Bandoliers
For 501st approval:
•At least one (1) must be worn across the chest or around the
waist.
•Must be of British 1903 pattern, Martini Henry, Turkish Ottoman or similar recreations, and matching the style in the movie. ◦Note: Swedish bandoliers are allowed for Level 1 original trilogy Tusken Raiders for waist bandoliers only, but are discouraged as they are not screen accurate.
For level two certification (if applicable):
• Only Tuskish Ottoman, 1903 and Martini Henry and the unnamed apparently custom made waist bandolier seen on the Tusken in the cliff flight scene are acceptable. Reproductions are acceptable for level 2.
They are a great buy they sell in the City Disposal store in Brisbane for $70. They are approvable for jawas a lot of us have them.
