Any truth to this? What part if any of the Norden sight did the
Germans utilize?

As already mentioned, they did indeed have Norden plans.

But Germany already had perfectly good bombsights capable of as good
bomb delivery as a Norden. Nothing so spectacular in that one.

For example the Stuvi sights used in Ju-87s and Ju-88s were highly
advanced, computerized sights for their day. They show that building a
advanced and accurate sight was not something that just the British or
Americans were capable of.
