Wow! Great P38 pics. thanks!
I heard the main problem with the p38’s in Europe was that at high altitude in the extreme cold the canopies would ice up and the pilot was essentially blind. Apparently the cockpit heater was either ineffective or non-existent.
The P-38 that primarily saw use in the ETO were the F thru H models. These had a complicated radiator system that ran thru the wings as I recall. It wasn't until the advent of the J-25 block models of the -38 with a new radiator layout that the engine problems were solved in the ETO. By that time though all but one group had converted to either Mustangs or Thunderbolts. The Pictures posted earlier were of "L" model P-38s, IIRC
Here is a couple of early P-38s...
A pic of the P-38 Glacier Girl which is an "F" model Lightning
One other note the P-38 was the only American fighter to be in production from 1939 to 1945.
