We extend our study of the nuclei of 3CR FR II radio galaxies through HST optical images up to $z = 0.3$. In the majority of them an unresolved nucleus (central compact core, CCC) is found. We analyze their position in the plane formed by the radio and optical nuclear luminosities in relation to their optical spectral properties. The broad–lined objects (BLO) have the brightest nuclei: they are present only at optical luminosities $\nu L_{\nu} \lower.5ex\hbox{$\; \buildrel > \over \sim \;$}4\times 10^{42}$ erg s-1 which we suggest might represent a threshold in the radiative efficiency combined with a small range of black hole masses. About $40\%$ of the high and low excitation galaxies (HEG and LEG) show CCC which resemble those previous...
