From the local library I borrowed a book called Der Adler (or something similair to that), its based on a German Luffewaffe magazine. The magazine was exported to the United States in english, and was also seen in French circulated in France and Belgium. Anyway there was a plane HE-113 featured in the magazine. It was a German night fighter, and I assume most of you have never heard of it, the reason you proably never heard of it is.... IT DID NOT EXHIST! It was placed bhind different backgrounds and guess what, it worked. Allied intelligence officers proably had a field day with those magazines. Enought for air crews to be briefed on the plane. On at elast occasion on a nighty raid, allied air crews claimed to have engaged some and shot one down. How can you shoot down something that does not exhist? Probably engaged and shot down a different aircraft, I assume it would be difficult to identify an aircraft at night.
during the BoB some raf pilots claimed to shot down a He 100, and that just because the propaganda campaing by the germans about this little plane
Well, yes and no. The He113 was a fictional designation given by the propagandists to the He100s to convince the British that the Luftwaffe had another front line single engine fighter. They did fly, they did fight as part of the Heinkel works defense squadrons, same as the FW187 did for Focke Wulf, flown in combat by the company's test pilots, so it is possible that one may have been engaged in combat and claimed for, I have no idea if any were actually lost to enemy gunfire though. It would seem extremely unlikely that any saw action over the UK though, but Air-Rec was notoriously difficult at the best of times. I have read that Mustang pilots were very nervous of P-47s when the P-51 entered combat in the ETO as the Thunderbolt pilots would see square-ish wing tips, inline engines and think "Messerschmitt 109". Similarly Bristol Blenheims were often mis-IDed as Ju88s. An early scrap in the war for the RAF, the Battle of Barking Creek ensued when Hurricanes were miss-IDed by Spitfires and two were shot down, one pilot being killed. All this shows that even in daylight aircraft recognition was a very difficult affair, at night it must have been all but impossible. I'd guess that the He113 could have been either a nightfighting Bf109D or an He100, but it's almost impossible to say.
Yes, the Germans kept painting the He 100s in different markings for propaganda pictures, so the Allies thought that the "He 113" was an integral part of the Luftwaffe fighter force. From what all that I've read, it maybe should have been, being superior in certain performance areas to the Me 109. But Willi Messerschmitt was popular with the Luftwaffe brass and Ernst Heinkel wasn't, so that settled that.
