Vintage Zenith Royal 755LG Portable Transistor Radio, Chassis 8CT41Z2, AM Band, 8 Transistors, Made In USA, Circa 1960
There are three major versions of the Royal 755. The first model, the LF, has a plastic handle which contains the ferrite rod antenna and swivels for best reception. However, grasping the handle diminished reception. With the second model, the LG, the ferrite rod was moved to inside the case. The last version, the LK, added a battery saver switch.
