On the B-font, I refer to several German news reports about the theft that made brief side-comments on the B being top-down (read it twice), and I refer to the German wikipedia site that identifies the man installing the letter intentionally wrong as
Jan Liwacz, a fitter/metal worker (Kunstschlosser) who was confirmed by several surviving witnesses of the camp to have installed the letter top down as a form of protest.
I certainly do not know all fonts in the world, but those I have seen or have installed in Word, see the upper and lower part of the capital B to be of either the same size, or the lower part bigger than the upper part - not the other way around. that is also true for text fonts used in Jugendstil. The upper half of the B being bigger than the lower half, I have never seen anywhere. And the font being used on that sign over the gate, are not that special at all.
All that does not prove you wrong Letum, I know, it could be that you are right. I just do not see a need for that more complex theory. If the reversed B would be a regular font, one would expect to see it in other German texts and signs of that time, too.
When they weld the three parts of the sign together again, they can use the opportunity to fix that B, right?
