overedge doublelobe or faint single source?
The geometry of the radio emission here seems suggestive that it is the lower lobe of a double, possibly associated with the lower-left of the bright overlapping IR sources to its 11 o'clock. I have seen single sources with comparable geometry but there is nothing at all in the IR that could be such a counterpart, although a radio galaxy too faint for the IR survey is a possibility.

Yep, this is a puzzler.
