Walter Stadnick personal RPO handstamp

1930s - 1950s

Railway Post Office (RPO) clerks purchased rubber stamps to mark facing slips and pouch/sack labels with their name, RPO route, train number, and date. Clerks were accountable for correctly sorting mail. If missent mail was discovered in their work by a receiving unit, the error was noted and sent to the district office of the Railway Mail Service (RMS)/Postal Transportation Service (PTS). The chief clerk assigned demerits for the error under the Service Rating System.
