Hi Michael,
Thanks for the interest in Courland. My day job will be quiet for the next month or two, so I hope to make some serious progress on the Courland book in the coming weeks. I've got more than enough Jagdgeschwader 54 material, so hope to obtain more about III./Schlachtgeschwader 3, Nahaufklärungsgruppe 5 and Nachtschlachtgruppe 3. The research phase is almost over, then it will be writing time.
So short answer: if 'real life' doesn't intervene, progress will be made in the final months of this year!
Cheers,
Andrew A.
