A couple other differences I've noticed;
Some backbox side brackets are exactly like the B/W (approx 3" wide), while some taper down to a point, like these last 2 picts.
Mine has the glass rails that don't wrap any part of the flipper button and the B/W type backbox bracket.
Have you moved the manual, or something inside, that may have moved your tilt bob closer to the side/edge?
It looks a little too orange to me... however, "if" mine was badly broken or missing, I'd be very happy with it.
