| WE 568HT telephone set - dated 1961 predates public introduction of Touch Tone service (1963). Intended for military communication on pre-AUTOVON network. P and SG keys (Priority and Special Grade) were for preceedence signalling and data/encryption function. Only style TT keyset with round line buttons that I am aware of. |
