Bit of a bumper reveal here – Fortress and Air Vanguard. I felt a bit bad just leaving you with two books for each so I bunched them together.
AVG 22: USN McDonnell Douglas F-4 Phantom II (March 2016)
AVG 19: Mitsubishi A6M Zero (September 2016)
FOR 110: Forts of the American Revolution 1775-83 (June 2016)
FOR ???: The Hindenburg Line (October 2016)
Next week sees the last of our series books. It's one of the big ones. Watch this space!
