  We constructed and presented in the first paper of this series a new sample
of 84 large angular size radio galaxies by selecting from the NRAO VLA Sky
Survey objects with angular size > 4', declination above +60 degrees and total
flux density at 1.4 GHz > 100 mJy. In this paper we present optical spectra and
images of those galaxies associated with the radio emission for which no
redshift was known prior to our observations. Optical counterparts have been
identified for all (but one) members of the sample. After our observations, a
reliable spectroscopic redshift is available for 67 objects (80%) from the
sample. This paper, second of a series of three, contributes to increase the
number of well defined samples of radio galaxies with ample spectroscopic
information.
