Hi Stig1207,
True, he did say that. But Bf 109s and P-40s were in North Africa at the same time in 1941 and 1942, and they DID clash. I said that North Africa may not have been the most important front for either the Allies or the Axis and, from that, I infer that Bf 109Es were likely still present in North Africa in 1941 - 1942. The P-40E may have come out in fall 1941 and, from that, I infer they MAY have been present in North Africa in 1942, when JG 27 was still stationed there with Bf 109s. They may or may not have had the Bf 109F at that time, I can't say.
I have heard a P-40 pilot who flew in North Africa speak, though I did not exactly pay attention to what P-40 sub-type he was flying, and he did not specifically say which Bf 109 model he fought. I generally pay attention to the opponent subtypes if they are mentioned in a talk, and SHOULD pay more attention to own subtypes.
So, absolutely no insult to Vincenzo at all, but I know P-40s fought Bf 109s in North Africa. What I do NOT know is the specific models that fought each other. He could be right that the Bf 109F may not have fought the P-40E in North Africa ... I don't know. But the Bf 109 and P-40 absolutely did fight each other in North Africa. The P-40 fought in every front the U.S.A. was involved in plus most that the British were involved in, and some the Dutch were involved in, and a few others, too. It was still fighting when the war ended, despite being out of production at that time. The Bf 109 was still fighting when the war ended, too, though it was still in production at the time.
Had I been the Germans developing the Bf 109F at the time, I would have been much more concerned with fighting Spitfires than P-40s, as suggested above, because the Spitfires were much better than the P-40 at higher altitudes that were common in Europe. In North Africa, however, the P-40 was pretty good below 15,000 feet where the North Africa air war was largely being fought. What I was quoting was a reference that stated the P-40E contributed to higher priority being assigned to the Bf 109F than it had before the P-40E. The reference is an old one, and maybe the inference was that the tail fix might have been speeded up. I have seen other references say that the initial "fix" was external longitudinal braces riveted to the tail, but have never pursued the truth of it. Actually, the only tail fix I KNOW had external braces was the Typhoon. I now doubt the old reference was accurate about Bf 109F development being tied to the P-40E and backed off from that above ... but it could be accurate. Yes, the Bf 109F came out in 1940 and the P-40E came in 1941, but the Bf 109F also had crashes due to tail failure in dives (Feb 1941) after it was first delivered to operational units in January of 1941, and required some rear fuselage redesign that may or may not have been pushed ahead for any number of reasons.
I doubt the P-40E was one of those reasons at this time since I think the Bf 109F was "sorted out" with regard to the tail fix before the P-40E was produced and made it to North Africa and became operational there.
Actually, if I go back and read some old books, such as Famous Fighters of the Second World War by William Green (1962), I can find a few things, though not many, in there I now believe to be false. Green states that in a vertical dive, the Spitfire could not stay with the Bf 109E. I think the Bf 109E had fuel injection and accelerated better initially in a vertical dive, but the Spitfire would catch it after the initial dive move was made. We KNOW the Spitfire has a higher critical Mach number than the Bf 109. So, I'm not surprised if an old reference is in error, and I should have paid more attention to it before posting above. It happens.
I am likely rambling now; it's late ... so I'll stop.

Cheers.
