Schiffer has published the first two books of the The Tiger Project series by long-time Feldgrau member Dale Ritter. The titles known to me are The Tiger Project: A Series Devoted to Germanys World War II Tiger Tank Crews: Book One - Alfred Rubbel - Schwere Panzer (Tiger) Abteilung 503 followed by The Tiger Project: Horst Kronke, Schwere Panzer (tiger) Abteilung 505 . Descriptions of both books along with some reader reviews can be found here on Amazon

Now I will leave it to Dale to tell us a bit more about his books and the research that went into them.
