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 ≥
,
declination above 
and total flux density at 1.4 GHz 
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, the second of a series of
three, contributes to increase the number of well-defined samples of
radio galaxies with ample spectroscopic information.
