Discordance of the unified scheme with observed properties of quasars
  and high-excitation galaxies in the 3CRR sample
  We examine the consistency of the unified scheme of FR II-type radio galaxies
and quasars with their observed number and size distributions in the 3CRR
sample. We separate the low-excitation galaxies from the high-excitation ones,
as the former might not harbor a quasar within and thus may not be partaking in
the unified scheme models. In the updated 3CRR sample, at low redshifts
(z<0.5), the relative number and luminosity distributions of high-excitation
galaxies and quasars do roughly match the expectations from the
orientation-based unified scheme model. However, a foreshortening in the
observed sizes of quasars, a must in the orientation-based model, is not seen
with respect to radio galaxies even when the low-excitation galaxies are
excluded. This dashes the hope that the unified scheme might still work if one
includes only the high-excitation galaxies.
