Small update, I was able to get a copy of the workprint. The video was unsalvageable, which is a shame as it would have been fun to find a way to work in the "You'll need a bigger cage than that" line. I was, however, able to use the line of Aaron saying "Vent shaft 17" instead of "Vent shaft 22", so I no longer have to cut Andrews saying "Vent shaft 17" as the continuity error has been corrected.
Took a little bit of work as the audio wasn't great quality either, but it should be pretty seamless.
