I hope your joking Oakranger....if not, here.
The P-38K-1-LO is the rarest variant, only one was ever built from scratch, another was modified from different model. So rare in fact that only photos that exist are of the heavily modified version. There are no know photos of the scratch built P-38K, the best preforming P-38 of the war. It had a initial takeoff climb of over 4,800 fpm and service ceiling of 45,000 feet or more! It was predicted to break 450 mph at critical alt while having 10-15% greater range.
This is the hot rod special of P-38s!
