The bottles were moved when the sextant was removed from the 245 wall. There was a lot of real estate available, so the bottles were moved back there.
Personally, it seems better if the armor is installed to have them mounted back there. BUT, I\'m not a crew member that would require a portable oxygen bottle at a millisecond\'s notice, so my opinion is not worth these keystrokes.
Maybe someone who was in the circumstance to need the bottle next to the seat can chime in.
There was a message/TCTO that came out moving the bottles back to the positions next to the seats. I\'d have to dig for that.
