I believe all the 200's have 5, but I could be wrong, too lazy to look it up now.
I remember something about the former EV 200s and pax O2 masks being different than the native 9E 200s. If it was total number of masks per row, or which side is which, I don’t remember, and a quick glance in the manuals didn’t bring anything up
