Q9-0 Harness?

[DazzlerFan]

I was curious if anyone has identified the chest harness and belt worn by droid Q9-0 in Chapter 6 of the Mandalorian “The Prisoner.” It looks familiar, but I can’t find a match. I’ve found matches (or near matches) for the pouches, it’s the harness I’m having issues IDing.

Thanks for any help.
