XY Toll Ticketing System Sounds

Carroll Lambert, a retired telephone company employee, has graciously given us several recordings of a Stromberg XY Toll Ticketing System that he recorded on a cassette tape around 1970. These were from a system that was in service at the Shenandoah Telephone Company (now Shentel) in Edinburg Va. during the 1950s to the 1970s. He retired from Shenadoah Telephone after 40 years of service. Warren B. French Jr. was President and General Manager of the company when all this took place. The Stromberg XY was removed when a North Electric computer controlled NX1E switch was installed in 1974.
