The last Testboard.
San Pedro, California

This testboard is the last of seven that were used from 1929 to 1985 in the San Pedro Central Office to test all feasible types of cable troubles involving residence telephones, business telephones, private lines and data circuits. It served San Pedro, Lomita, Wilmington, and parts of Torrance. It was replaced in 1985 by MLT-II (Mechanized Line Testing.)

The current location of this antique is a closely guarded secret.
