    This Regency TR-1 is fitted with a clear case and was intended for demonstrational and promotional purposes only.  Each transistor is painted with a two color code scheme for easy identification.  This particular set is owned by Bret Phillips of Spartonburg, South Carolina, who believes, basing on reliable sources, that there were only two production, clear case, Regency TR-1 radios ever manufactured and both still exist today.  Regency also produced a few TR-1s who's cases featured standard colored fronts and clear backs.
