Ok, I did read this on Wikipedia, so may not be true, which is why I am on here to find out the true answer, but it states that the following aircraft are 10 abreast in Economy instead of 9, like the rest of the B777 fleet.
This was a now defunct joint venture between BA and, if my memory serves me correctly, Flying Colours, under which the latter operated high density DC-10s and subsequently high density 772s (G-VIIO, 'IP and one other) to Caribbean and Florida (TPA) holiday locations in BA colours and on behalf of BA.
When the venture was wound up the aircraft concerned were reconfigured with a much lower density configuration but still operate the same routes together with a similarly configured fourth aircraft (G-VIIT).

MSN is the airframe number (Manufacturer's Serial/Sequence Number), and is allocated by Boeing (in this case) when an airline or other customer confirms an order. Every Boeing airliner (or airliner derivitive) has a unique MSN within the same Boeing range, but beyond that they have no significance, as they don't indicate build sequence or delivery sequence. Build sequence is best determined by Line Number (i.e. production line sequence number). Because all Boeing airliners have MSN's in the same series, each production line (e.g. 777) has its own Line Number sequence; other manufacturers generally just have a single series of numbers for each type (the exception being the former Douglas, who used the same system as Boeing, i.e. manufacturer numbers and line numbers).
