This is a crewman's bucket used in the 2001 Russell Crowe high-seas adventure Master and Commander: The Far Side of the World.
Buckets such as this can be seen in the film as Capt. Jack Aubrey leads his crew in hot pursuit of a French Privateer.
The small bucket is made of wood and has three sturdy metal rings around the perimeter. Additionally, the bucket has a rope handle attached to the bucket as well as the wooden lid.
It has a small label on the bottom which reads "Disney Studios Prop Dept." along with a bar-coded number. This detail further enhances its autenticity and provenance.
