sycamore, I was about to call your bluff, but it appears you are correct regarding the early Lightnings of the RAF. They not only had same-rotation engines, but no turbos either. I found this at:
About the P-38
However, all US P-38's did counter-rotate. In fact there's a limerick set to a ditty tune "Fighter Pilot's Lament", one chorus of which goes:
"Don't give me a P-38
With propellers that counter-rotate;
She loop and she'll spin
and she'll augur you in,
Don't give me a P-38!"
