Mr Asisbiz was more than happy to copy and paste my entire article to his website without permission, but neglected to mention my old Focke-Wulf 190 site (

Friedrich Jost did not make a claim on 13 August 1942: his nearest was 17 August 1942.
Unfortunately, I haven't looked into this fascinating topic in many years, and Chris was a great help when I wrote the original article back in the early 2000s.
Cheers,
