It's most likely on loan over there as some Bronx buses are running down at Quill like 4983 from West Farms and 4340 from Kingsbridge. A Nova LFS from Kingsbridge was running on the M42 earlier today too.
Edit:4938 is still at ENY. Currently on the Q24. You must of seen 4983.
This is more subjective as while fans are fond of bus sounds, the average crowd could care less or would rather want the bus to be more quieter than the previous buses.
Those two units were always shared with the other SBS routes operated by Quill. 5965-66 didn't have luggage racks like the other 5900's at Quill as they were former West Farms units so it made sense that those units were swapped instead of those with luggage racks.
Ulmer Park how its set up now won't be able to inherit any of the routes you suggest without having to lose some routes as the depot can't be crammed with even more buses that they can handle, mostly with getting the B49.
Its not joking about the fact that the B1 could use some artics, it was only joking on that Ulmer was going to start training just cause a Nova LFSA was signed up as a B1 in the Quill depot.
Lol, it was a joke made by some on the members of the transit page on Facebook.
Some people actually believed in the post, that's how gullible some people are.
I was referring to a SBS unit swap, not a swap of regular artics like the one you're referring to.
5128 and 29 were never sent to West Farms, the had 5127 a few months ago before heading to Quill. 5128 and 29 came from Jamaica.
There really isn't a swap going on for Bronx and Manhattan SBS units. No Manhattan SBS units came up here in exchange for now so its too early to say if a swap will go down.
