I'm hoping to get an identification on this box for both present and future use.

It appeared to be a standard 4" x 4" 1900 from the appearances of the inside KO's... although I did wonder why there wasn't a blank side where the bracket was... Then I cut the wall to change the ring and got my answer.
It appears that a 1G 5/8" Ring is ONE with the box and there's a front facing bracket to the right.
I've never seen a 1900 where the ring is ONE with the box
Masonry boxes, gem boxes, etc. sure... but this one is a new one to me.
Anybody seen it before?
Thanks.
