Konstantin Feldman, who played the part of the "student agitator", was actually a Menshevik activist in Odessa at the time of the mutiny and was present on the ship during the latter part of the mutiny. He died in the Stalinist purges of the 1930s. (N. Bascom, "Red Mutiny" p. 294--although Bascom says Feldman played a sailor.).
