Hello BIGVERN1966
Harrison p. 54 on 12/13 Dec. Lt Jimmy Kneale with Lt G. L. Davies DSC, the serial is not clearly stated (at least I cannot say that am 100% sure but it’s almost midnight here and I have spent 12 hours in archives and library today), but most probably MB419 (BTW the photo is of MB564 and credit of it is given to Lt/Cdr J. H. Kneale)
Then “He recalls the trip: ‘Only on one occasion was a Firefly NF1s cannon fired after a long ASH controlled pursuit in low-lying thick cloud which prevented any visual identification of the target. In the absence of a blind-firing facility this was no more than opportunist attempt, and no result were claimed.’”
