Incredible source! It looks like one of the tails takes a sudden bend. The parent galaxy has no redshift, although bright, but it is almost certainly a member of the IC1365 group. No previous study of the radio, as best I can tell. One of WINGS groups, so lots of optical info. Worth following up.
Here's the larger field with X-rays on the left.
NED says the main galaxy is 2MASX J21132669+0231233, with a measured redshift of 0.049, per this 2004 NOAO Fundamental Plane Survey paper. It also has a published redshift of 0.048 in this 2012 2MASS Redshift Survey paper, and in this 2009 WINGS paper.
It appears to be one of the ~12.5k radio sources covered in the 2007 Jackson+ paper, "A survey of polarization in the JVAS/CLASS flat-spectrum radio source surveys - I. The data and catalogue production".
