ARG0001e75, QSO, overedge, hybrid, restarted, triple?

Here's ARG0001e75, which includes the emission to the N, that is #overedge. This is a rather complex field, with a number of emissions, and ARG cross references, most notably ARG0001e79.
The contour overlay image in this post was created from sources, and using methods, described in this RGZ Talk
thread.To begin, the host for the emission in the centre of the image, also listed as a #QSO, is SDSS J172109.49+354216.0, which has a z_sp=0.283 +/-0.00002. First flux emission is listed, and this is apparently an #overedge #hybrid, #restarted, #triple, which has a size ~2.2' = 530 kpc, according to the classification comments noted in ARG0001e79. The emission appears to extend to the north and south and there are also a number of radio references in NED and SIMBAD for this galaxy, and its emissions.
Just south of SDSS J172109.49+354216.0 is SDSS J172109.72+354138.2, which SDSS DR13 lists as a star, and has recorded First flux emission in SDSS DR13. There are also radio references in NED and SIMBAD for this object, and there is a DR7 z_ph=0.065 +/-0.052. DR7 also lists this object as a galaxy.
And to the north there is recorded First flux emission, centred on SDSS J172109.08+354314.2, which SDSS DR13 lists as a star. SDSS DR6 notes that this object has a z_ph=0.604 +/-0.023, and there are radio references in NED and Simbad for SDSS J172109.08+354314.2.
With the above in mind, is it possible that some of this emission is coming from separate objects, rather than just from SDSS J172109.49+354216.0?
Here's a First image of the emissions.
As always, comments, suggestions, welcome.

Rather mysterious, eh? 😉
I'll add one possible host, (blue) STAR SDSS J172108.49+354314.2, for the N cloud ... perhaps we are looking 'down the barrel' of a pair of (overlapping) lobes from a now dead AGN (jets shut down a long time ago), but the lobes haven't yet become so faint and diffuse as to be all but invisible in FIRST.

Wonder if SDSS J172108.49+354314.2 is a #QSO?
Also maybe SDSS J172108.12+354309.8, which has a z_ph=0.564 ± 0.0442. Has an ALLWISE reference, ALLWISE J172108.09+354309.6.
