It is. MB757 was a Mk.1 used as the mock-up flight trials aircraft for
the Mk.7. Joseph Testagrose's previous photo of MB757 shows the dummy
rear cockpit cover before the clear one was fitted.

I'm getting this information from Fairey Firefly by Joseph Harrison,
Airlife 1992, ISBN 9781853101960. One of these days I'll actually read
the whole book.
