Here's ARG000223y, two Wat's. Quite a spectacular image, although very hard to pin down the sources of both the emissions.
The contour overlay image in this post was created from sources, and using methods, described in this RGZ Talk
thread.The lobe to the SE is centred on SDSS J082843.10+243602.3, possibly the host, which has a z_ph=0.264 ± 0.1107.
However, NED has a number of Radio references for SDSS J082843.65+243552.9, which is SE of SDSS J082843.10+243602.3, and has a z_ph=0.261 ± 0.0915.
The lobes to the NW are more problematic. NED and SIMBAD do have a reference for SDSS J082838.74+243707.2, which has a z_ph=0.399 ± 0.1280. However this galaxy is quite of centre from the core of the lobes.
The lobes could be centred on SDSS J082839.03+243653.2, a #green galaxy, with a z_ph=0.247 ± 0.1027. However, this galaxy has no radio references.
The ARG classification comments of #noIR and #nooptical seem quite apt for the NW lobes.
And here's an ALADIN overlay. Red dots are ALLWISE sources. Any further suggestions for possible hosts, or not, are very welcome!

The DECaLS image of this field is interesting; this cutout covers much of the upper (N) WAT:
I'm new to DECaLS, so I'm not sure how to best get the cutout I want, nor how the bands map to RGB (JPEG) colors ...
