Technically, IIRC, what the CAF has is actually an LB-30. It’s close to, but not exactly, an early B-24. There was another flying B-24J, but it’s passed through a few hands and is currently out of action.
Hard to believe that, out of almost 18,000 B-24s built, there’s only about thirty left (if that). Interestingly, most of the survivors came from India, which pieced together two squadrons’ worth from demilled planes left behind by the British and used them as patrol bombers as late as 1969.
Gadzooks! I was just reading... about that at http://www.bharat-rakshak.com/IAF/History/Aircraft/Liberator.html
