Here is a nice working RCA model T-2-K.  It is a 6 transistor radio in a faux leather case.  This radio was manufactured around 1959.  It is powered by 3 "C" cell batteries.  The radio works great and t sounds good too.  The case is in very good condition also considering the radio is almost 60 years old.  This radio is commonly called a coat pocket size because it measures about 5" wide X 7" tall and 3" deep.
