In reply to I'm finding a number of 1948… by mybulova_admin
My thoughts as well. Original Aviator was unengraved rose gold. Based on available ads, at some point in 1945, Rose gold unengraved Aviator became Aviator"A" and Warrior (engraved yellow) became Aviator "B", hence the 1946 ad calling out "engraved Aviator" ( a "new" Aviator model).
Per examples in the Db, 1945 dated Aviator "B" and later shows face with "7" having hook at bottom. Warrior has straight leg "7". It appears that the first engraved Aviator ads (45/46) recycled the graphics for the Warrior, showing straight leg "7".
Take note of hand placement in ads. Aviator "B" ads use same graphics except the minute hand appears slightly longer and thicker to partially cover the bottom of the "7" . Pretty clever.
