He is equipped with a Thompson M1928.
The man was hired by Carl Denham to an expedition to Singapore (never telling him and the other crew that they were actually going to Skull Island). He was along the crew getting ready to captured Kong. He was seen next to Venture Crewman 21 and Venture Crewman 23 and next to the sailors who were station by the hut. Its possible he escaped along with crew when Kong broke free and live to tell the tale.
