Here's ARG0002ci9, which appears to be a #one-sided, #bent, almost #slip-strike, #doublelobe.
The contour overlay image in this post was created from sources, and using methods, described in this RGZ Talk
thread. First in red.The host for the emission appears to be SDSS J102901.24+201006.1, which has a z_sp=0.111 +/- 0.00002. This galaxy has radio references in SIMBAD, an ALLWISE reference, ALLWISE J102901.25+201006.2; and recorded First flux emission.
Interestingly, this galaxy is listed as the brightest in a #cluster, and appears to be #merging or interacting with SDSS J102901.31+201032.1, which is north of SDSS J102901.24+201006.1. SDSS J102901.31+201032.1 has a z_sp=0.111 +/-0.00006.
And finally, there are radio references in NED for SDSS J102901.26+201014.2, which is listed as a star. This object is positioned just north of the south lobe. Whether this object is the host of the emissions is hard to ascertain.
As always, comments, suggestions, welcome.

Very cool, well done Chris! 😃
The host of the S emission seems unambiguous, but what is the host of the N emission? If it's within the VLASS footprint, maybe VLASS data could help? Not only does VLASS have higher resolution, it's also deeper (the frequency range is different, ~2-4 GHz vs 1.4 GHz).

in response to JeanTate's comment.
It doesn't appear that this one has been imaged in VLASS. VLASS Quicklook Sexagesimal co-ordinates list it as not being imaged; Decimal lists it as having been imaged. A file for the sexagesimal co-ordinates doesn't appear to be in VLA Sky Survey Quick Look Images
