Western Electric 684 Anti-Sidetone Subset

Western Electric 684 anti-sidetone subset with coil, condenser and ringer.. The 684 was used in conjunction with the A, B, C, D, G handset mountings. A 4 conductor subset cord is required to connect this subset to the phone. Measures 5 1/2" x 7 1/4" x 2" deep. Please note that due to the scarcity of original tops, our 684 subsets will now have HIGH QUALITY reproduction tops. Thank you
