Squire, did you miss this comment? "Jester, however, has a references October 44 entry date. It's a toss up really but I'm sticking with this setup. "
Yes, I understand there are references to a much later service date, but your data is the THIRD different service date I've seen... (sigh). On a side note: the link you referred to is a 'personal' site and the data on any 'personal' site is as subjective as a Michael Moore film... Not accurate, but a pretty good reference point.
Now, if you could answer when the P-51D entered service, then I'd be willing to scoop up that info... wait a minute... I've got an idea. See my next posting...
