Hiya Jeeves,
There's nothing in that Osprey book for the 99th FS, but I think that's because the 99th FS was still assigned to the 12th AF when they flew Bolts. I'm really not 100% sure on that, I'll have to grunge about or maybe someone else knows fersher. Off the top of my head, does Osprey publish a similar title for the 12th? I gots to go lookin'...
As to the P-39 & P-40, I can't help much on the P-39. But the P-40 may be a different story, I'll see what I have. I've got a couple books and lotsa misc reference on the 79th FG, so there may be something among all that for the 99th.
The Osprey book
'P-40 Warhawk Aces of the MTO' has one profile of a 99th ship; a P-40L flown by 1Lt. Robert Deiz. I haven't looked closely at the rest of the book to see if there's any additional photos or what-not, but I shall...
Fade to Black...
