First one to correctly identify wins the satisfaction of a job well done!
EDIT: Fed(oo=||=oo)uken wins! It's a PB4Y-2 Privateer. I'll let ttyymmnn explain:
Both the Liberator and the Privateer, a maritime patrol plane, were developed by Consolidated. The Privateer was a bit longer than the Liberator, and obviously had a different empennage. The engines were also not turbosupercharged, since they wouldn't be flying at the same altitudes as the Liberator.
Thanks for playing! Until next time...
