I believe this is a 300 series phone dating from the 1950's-60's (possibly model 332): serial number L11560C7 is printed on the base. The phone has the original black rotary dial, the original white number plate with red numbers / black letters under the black dial, and the original braided cord.
The Vintage GPO Bakelite Black Rotary Dial Telephone is a fantastic choice for those seeking an authentic piece of 20th-century British telecommunications history.
