Many thanks for the responses.
Joe Baugher's site is one I frequently access Glenn, unquestionably the bast for US military.
I have already branded Skyhawk as Douglas. I can see no sense in the random use of McDonnell Douglas but am happy to revise if further information surfaces in the future.
Out of interest I reviewed Joe Baugher's entries for the Texan II but it hasn't proved helpful.
1995 - Beech Raytheon
1996 & 7 - Raytheon
1998 - Beech Raytheon
1999- Raytheon Beech
2000 - Raytheon
2001 & 2 - Raytheon Beech
2003 to 10 Raytheon
It almost seems as though the complexity eventually became too much for Joe and he finally plumped for calling them all Raytheon!
Bearing in mind as pointed out that other models are similarly affected, could we find a consensus view, particularly from our US friends as to how I should proceed. As with the A-4, it makes little sense to leave the entries as they are.
