4616 is not retired.. The unit worked both on the B41 and B46 on Wednesday.
4606 also not retired. This unit worked on Monday and Wednesday.
Also, I'm questioning a few of the units from FB.. Some of these units just worked last week & Monday. Responses in Italics
4333 last ran on the B44 on 12.12.22 (not retired. I think this unit is on a break)
4591 last ran on the B49 on 11.29.22
4595 last ran on the B31 on 12.14.22 (not retired. Also, I think unit is on a break or possible MTA bus transfer)
4603 last ran on the B49 on 12.9.22
4606 last ran on the B46 on 12.16.22 (Back in service as of 12.21.22)
4616 last ran on the B41 in 12.17.22 (Back in service as of 12.21.22)
4629 last ran on the B41 on 12.16.22 (not retired. Also, Unit may be on break)
Unless these units have fareboxes removed I'd give it some extra time for this.
