Les no not really although he is taking some first person accts from JG 54 and Jg 26 vets possibly from that book to supplant the ones from JG 301, JV 44, JG 6, etc........the book is going to be a monster with many profiles and unknown pics
sad but I already own the JV 44 booklet and of course the big JG 54/JG 26 book he did several years ago and with the 7 or so signatures, got to know one of the pilots that signed the book, sadly he passed on. I paid a whomping 175.00 for the Dora-Grün Herz but it was worth it to me as I had the one pilot do some signing of pages and photos when I picked the book up from Jerry/Judy and the German vet in California when it was first published.
the "new" book will also have some very unique fotos and signed by 9 ? personalities, one is the former Gruppenkommandeur of II./JG 301 Cescotti who was a bomber recon pilot originally
