The ONLY Flying A-26A Counter Invader in the world!! Now Restored and FLYING! 

This B-26K is a World War II A-26 Invader that received extensive modifications for the Vietnam war and was renamed the A-26A Counter Invader for political reasons. This is the only A-26A/B-26K that flies, that we know of. This is NOT a Martin Marauder B26, but a Douglas Invader A-26A.
Short naming history for this aircraft:
Built as A-26B or C, renamed B-26 after WWII when the Martin Marauder B-26 left service, then B-26K after the On Mark conversion, then A-26A because Thailand wouldn't allow bombers in Thailand during the Vietnam War.
This is the Denny Lynch aircraft from Billings. It has been stripped of its paint for restoration.
This is NOT an A-26B Invader. Two visible clues, 4 hard points on each wing, and tip tanks.
