Lot is for a vintage "pocket" (handheld) transistor radio from REALISTIC--this is the Model 12-634 AM FM Integrated Circuit radio, made for RADIO SHACK.  This features a wheel switch for power and volume, and another wheel adjustment for tuning the station.  Has a complete sectional antenna, and the frequency selector switch is on the back.  Runs on one 9 volt battery (not included).  Tested and works well.  See photos.
