Here you see the FT family: (left to right) FT 70 by MIVA with the embossing of TE.TI. telephone co., FT 80 in white porcelain by RICHARD GINORI, FT 92 in a rare porous brown material version, and the big FT 120 in black porous material with the mark of STIPEL - TELVE - TIMO telephone companies. The FT family is the 1st modern insulator, that abandones the top groove, after the unlucky experiment of TS 1 FP of the 1947.
