There is no secondary supply other than the portable bottles in the cockpit (one on the bulkhead, one inside a stowage bin with roll-down door).
Even the so-called Boeing spokesperson got things wrong. There are definitely not "dozens of bottles".

Really? There's no automatic shuttle valve between flight crew tanks? That could be considered a "secondary source" even though the crew does not have to select it......
Are you sure that all the lower hold crew oxy supply bottles (fleetwide) are not composite and coulored white? You're positive about this?
