Dear mr. Prien
Thanks for the comment. This is one of the situations were a reader has a real problem, the photograph as reprinted in the book is just not good enough to make the WNr of the aircraft in question readable. And as Merrick has identified it as WNr 10681, this is what we would be looking for in our databases. And as You might suspect, I have not found a correspondance in my database for the mentioned WNr and a Stab aircraft for JG 77 or JG 27.
The aircraft you mention is registered as follows:
http://www.ahs.no/ref_db/lw_loss_pub...?lossid=106682
and that the unit did use these kind of markings are shown in the following record:
