Identified with the E galaxy UGC 12064 in the poor cluster Zw 2231.2+3732. HST images of UGC 12064 show a prominent dust disc with its axis at PA 65°; thus the jets are not emerging perpendicular to the disc.

At high resolution, the central region of 3C 449 is one of the classic examples of weak-flavour twin jets (Perley, Willis & Scott 1979, Corwall & Perley 1984). These jets make up the slightly fainter region between the two bright peaks in our image; at higher resolution the peaks are resolved into extended components with surface-brightness substantially less than the jets.

3C 449 is projected behind the faint HII region S 126 in our own galaxy. When displayed at high contrast, our C20 image shows faint radio emission from S 126 crosses the lower half of the DRAGN (Andernach et al. 1992).
