OK, all of this I knew except the part about Hitler changing the designation of the Bf 109. I always heard it that Willie added his name in the form of ME just as you say, but that it started (I believe) with the ME163 and from then on all Messerschmitt aircraft carried the ME designation. I know that I've only seen the Bf 108 and Bf 109 series of aircraft listed as the (for example) Bf 109E-3 and I've never seen it as ME109E-3.
In my Humble Opinion, The Swallow is the most beautiful aircraft ever to grace the heavens with it's presence.
