Partial-synthesis maps are presented for a sample of extended radio galaxies at 2.7 and 8.1 GHz. These maps were used to determine the overall sizes, orientations, and gross morphologies of the sources during a study of the relative orientations of extended radio sources and their parent elliptical galaxies. The optical identifications of 13 sources have been confirmed by the detection of small-diameter radio components within their parent galaxies. Two radio galaxies in this group - 0238 + 085 and 1250 - 102 - have extended radio cores and elongated structures suggestive of two-sided radio jets similar to those of 3C449, NGC 315, and 3C31. The spectrum-luminosity relation found for extended radio cores in Paper I of this series has been confirmed using spectral indices of improved accuracy.
