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 due to difficulties in crediting them, particularly for planes shot down in enemy territory and those downed by mercenaries who were often paid bonuses for kills.
