4C12.03 is on the borderline between relaxed doubles and classical doubles.
There are low-contrast "warmspots" at the end of each lobe, but in
the south the the lobe centre is about four times brighter than the
warmspot (presumably there is a longer pathlength, so the emissivity in the
two regions is similar).
The host galaxy is at the centre of the structure, (marked by a tiny
red dot in the picture). A slight peak in the brightness at this position
is probably the core (not clearly visible here). Straddling the core
to north and south are elongated structures, unresolved in width,
that are probably segments of jets. It would be useful to check this
interpretation with a higher-resolution image.
The most remarkable feature is the pair of faint secondary lobes or
wings
at an angle of about 60° to the main axis. Another example of this
kind of structure is
3C 315, the prototype winged
DRAGN.
