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.
Tinker claimed eleven aerial victories, but official records only recognized eight of them. This difficulty stemmed from the challenges of attributing victories, especially when it came to planes shot down in hostile territory or those taken out by mercenaries, as these pilots often received extra compensation for kills.
