Specimen ratchet and tongs No. 2, for 100-200 pound wire, made by the General Post Office, British, 1900-1969.

These sets of ratchets and tongs were part of the equipment used for maintaining the correct tension in telephone and telegraph wires. Different types were used for different weights of wire.
