Well, it seems the mystery is solved. I sent several photos of this Soldbuch to Emilie Caldwell Stewart. She addressed the fact that the signature on page two of the book is a dead match for the signature on the inside cover and concurs that this is a war-time replacement cover, she sees no problem at all with it. Also, however faint...the Hohenstaufen stamp can be seen on the inside cover photo. So, I will try and get it to the for sale forum this weekend.
