1991 US LD and 1997 Bravo TV are the same source; the 2004 DVD R1 and 2010 Blu A/B/C are the same source as the 1992 UK LD.

The implication is that the original source was lost/damaged/whatever, and so they used the same source that was used in the 1992 UK LD.

What do you mean it's the same source? Do you mean the same film print? If so, how did you find that out? Cropping is hardly a good enough indicator for judging this, as most prints have pretty much the same cropping as the oneg and the cropping seen in those pictures was done when mastering the discs and most likely has no information value whatsoever as to the cropping of the source prints.
