Movie of the pre-2000 type final selector working 506 is dialied to call the black wooden 221 phone which you can see on the right of the exchange (1st digit dealt with on upper rack). This is part of my collection of old GPO strowger equipment. Actually this final selector comes from a PAX and is one of two I own from the same PAX, but I have not found out where they came from. It differs slightly from standard GPO practice. It has a recall holding feature common with PAX equipment, but it uses earth testing rather than the battery testing found in later PAX equipment.
