Any known Ar196 losses for 17-6-44 ?

You are correct. In the 100--- series there is a gap at least between 100385 and 100428. According to the Stammkennzeichen series
100385 had CT+KE and 100428 CT+KH. Consequently two more aircraft are there somewhere. Only rarely were there breaks in the middle of a Stammkennzeichen series. I have histories for both 100385 and 100428. I hope your friend could find more about the Fokker W.Nr. I only have seven aircraft in this series and that is not much to build on. Most of the Fokker production was delivered in 1944, but even for the first six months of this year, very few aircraft is mentioned with Fokker c/n's. Part of the problem is that in many cases only the last three digits of the W.Nr. was reported, making it impossible to know if it was an Arado-built or Fokker built aircraft. I hope someone can assist in this discussion, which by the way has turned completely off the original topic.
