Hmm. Officially, 25 Sqn were still on Blenheims, getting the first Beaus for conversion training in October 1940, and completing conversion by January 1941. Although it's possible the Beaus saw action in the later stages of the BoB, I haven't found any definite evidence, and they moved to Debden (from North Weald) on 8th October.
There's always the two '600' Squadrons, or there's a possibility of R2204, FK-J, of 219 Sqn ?
If the pic of the 25 Sqn Beau doesn't show the 'arrowhead' antenna, or the wing di-poles, then it might have been deleted by the censor at the time. Or, of course, it might not have had the A.I. fitted at the time, which would almost certainly mean the aircraft was not operational as a night fighter.
