Assuming that this isn’t just a copying error and the pages are indeed missing from the paper copy then it’s likely they are gone.
There are/were pages missing from the microfilm copies but in my experience these were usually present in the paper copy held downstairs.

If it is the same aeroplane then that is a historic artifact and poignant memorial permanently ruined and questions need to be answered.
Somewhat ironic that the original pictures were dismissed as ‘a model’ when this seems to have now been painted to depict a particularly poor one too.

The text says that it replaced the upper turret but surely that installation is in the radio room?
(at least it appears to be with my eyesight and a mobile screen)

There is a F/Sgt HWB Greetham 620817 commended for valuable service in the air 8th June 1944 in The London Gazette.
Not unknown for given names to bear no relation to that which someone is known by, but probably the wrong man.

I think it might be time to start being careful before overly extensive quoting breaches copyright.

There was another sequence of Hurricanes in flight which was clearly reversed.
The footage was very ‘illustrative’ rather than specific and a lot used in that episode is the same as that in the identically titled episode of The World at War (albeit that there is a degree of inevitability in that).
