ok i'll get an 'early' boxing if they're still available when i'm caught up on all the kits that are likely to go extinct. i *need*--as in, i'll die if i don't get--the Eindecker in which Udet got his first kill and Barker's Snipe, so i'm optimistic.
Got the Cross & Cockade/RAF Museum FE2b/d book, it arrived today. this is probably the best book on a single aircraft type i've ever seen. it's jaw-dropping. Of the rest of the books you've got, are any of them essential beyond the Windsock?
Libby's book is also available as an audiobook btw. that's how i 'read' it. the 'd' i may build as Harold E. Hartney's, if his books are good. just started reading him. if not, i'll pick an ace with a gaudy scoreboard (there are a couple, the Fee was a formidable beast).
