Forms P1, "Passenger list - Outgoing Passengers" were prepared by the masters of ships departing the port and show the name of the ship and other details including the voyage details (port of departure, destination and date of departure) and list passenger details (name, nationality, sex, age, marital status, occupation). The P1 form was replaced by Customs forms M310 and M310A in 1964. The series was discontinued with the closure of the agency recording in November 1987.
