Railway Post Office (RPO) practice and examination kit used by St. Paul postman Richard Loida between 1946 and 1956.  Loida frequently worked on RPO cars headed from St. Paul to Duluth, North Dakota and South Dakota.  The kit’s main element is a hinged wood case that opens to reveal a rack with approximately 88 slots in each side.  Included are cardboard cards that bear the name of a Minnesota post office.  The rack is a miniature version of the slot system used on RPO cars; slots are labeled with Minnesota railroad junctions and destinations.
