US Navy markings for US squadron during Battle of Midway

[Gelber Komet]

Hello, I would like to ask do anyone have website or book that good as reference for US Navy markings for US squadron during Battle of Midway. Since I still have some confusion that designated letter (F, T, B etc.) still retained or get omitted? From my understanding it still mixing between designated role letters and aircraft number vs aircraft number alone? Please correct me if I'm wrong.

Thank You
