ARG0001xuh, multiple emissions and hosts

Here's ARG0001xuh, which seems to be a complex, #overedge emission, with multiple lobes and possible hosts. The contour overlay below is positioned on SDSS J124619.30+262636.6, which is NE of the ARG co-ordinates listed left. This ARG field is also cross referenced in the following post: ARG0001xuh 3 GALAXY RADIO SOURCES ?
The contour overlay image in this post was created from sources, and using methods, described in this RGZ Talk
thread. First in red.In the centre of the emission there is a #diffuse #compact lobe, which is positioned on SDSS J124619.30+262636.6. This galaxy has a z_ph=0.338 ± 0.1347, recorded First flux emission, and a possible ALLWISE reference, which is slightly SE from this object, ALLWISE J124619.44+262635.5.
SSE of SDSS J124619.30+262636.6, there is another #compact lobe positioned on SDSS J124620.00+262609.2. This galaxy has a z_sp=0.089 +/-0.00001, recorded First flux emission, and radio references in NED and SIMBAD. It also has an ALLWISE reference, ALLWISE J124620.00+262609.3.
To the NE there appears to be a very #extended #NAT, which possibly stretches to the centre N of the contour overlay. A possible host for this emission could be SDSS J124621.86+262716.8, which has a z_sp=0.087 +/-0.00001. This object has radio references in NED and SIMBAD, and an ALLWISE reference, ALLWISE J124621.85+262716.9. There is also possibly a faint inner #ring in this galaxy, but GZ2 classifications cite this galaxy as being more smooth and elliptical with no apparent #ring.
Of note, SDSS J124619.30+262636.6 could also be the host of some or part of the #NAT. There is also the chance this object could be the host of a #triple with parts of the emission to the SW.
There is a radio reference positioned NNE of SDSS J124621.86+262716.8, which could also be the host of some or part of this emission. SDSS J124622.33+262744.1 which has a SDSS DR12 reference, could be one host, as per the radio reference citing in NED. This object is listed as a #star, but is very faint in the image below. There is also an ALLWISE reference slightly NNW of this object, ALLWISE J124622.02+262748.8.
The emissions to the SW have a couple radio references positioned on them. What the morphology of these lobes are, is hard to determine. They could possibly be a #triple, or a #unusual #wat, or a #double and #compact and #nat, and there is even the possibility of an #overlap on the west side of this emission.
There is a radio reference in NED positioned on SDSS J124616.81+262532.4, which has a z_ph=0.178 ± 0.0544. This object also has an ALLWISE reference, ALLWISE J124616.82+262532.6. This galaxy is positioned on the south edge of the bridge emission of the main two lobes, more to the east.
And there is a radio reference in NED for SDSS J124615.04+262557.7, which has a z_sp=0.085 +/-0.00002. This galaxy is cited as an #AGN, has a radio reference in SIMBAD, and a couple of ALLWISE references, ALLWISE J124615.19+262557.9 and J124614.86+262557.6, respectively. This object is positioned on the NW edge of the SW emission, and could possibly be the host of some #overlapped background emission.
Finally, it seems a large number of these emissions are in #cluster, #group environments, which could explain some of the more unusual morphologies, especially with regard to the SW emissions. Also, some of the emissions appear to be from more distant redshifts adding to the complexity of this ARG field, and what the morphologies are.
It appears that this ARG field has been imaged in VLASS, but the fits file has not been loaded as yet. I have looked high and low for this file and can't find it, except for a cutout in Quicklook.
As always, comments, suggestions, welcome.
