 A book presently available on this topic is "Airmen Without Portfolio" by J.C. Edwards, devoted to the memory of FG Tinker.It refers to entire paragraphs from "Some Still Live", including pictures of Tinker and his handwritten flight logbook.Tinker has claimed a total of eleven victories but was credited officially with only eight - it was very difficult to credit victories at that time especially for planes shot down in enemy territory and for planes shot down by mercenaries, because mercenaries were often paid bonuses for kills.
