Which is correct? I don't know, but most of the sets with a socket seem to have been made around 1951, or just before the CBS system was set to launch.
If the set with the socket was an Admiral or a CBS Tele-King, an Admiral color adaptor model CA-101 could be installed under the chassis of these sets. The CA-101 would adapt the set to receive and display either NTSC or CBS color signals *IN BLACK AND WHITE ONLY*. The socket was for a color wheel system [supplied by others] for use with the set to display the CBS signals in full color. Admiral never made a color wheel for thses sets but Webster-Chicago did. There are images of the W-C color wheel in use in several 1950s TV repair books.
