I have a suspicion that 744 may refer to the British s/n AR744.
Looking at its AM 78 card it was SOC 20.6.1943 plus an odd additional note:
"Brought back on charge" with the authorization dated 18.2.1944, all of which in turn has been crossed
over!
As we all know the French held those strange letters before the s/n in great "contempt" (
) and very
often never bothered recording them.
Not impossible it may have been turned over to the French
Does that fit in with your dates as well?
No 74 is not possible, shot down during the French campaign
No 44 could be a possibility, if it was repaired after its very bad landing at Etampes in 1940.
Aircraft does not show up anywhere during 1941 though.... (that is how far I have gone through
my data available)
Cheers
