Well Jim, that ad certainly confuses it. Now, per ads in the Db and beyond , we have the first documented verified 15J Aviators as unengraved in rose gold. We have an ad dated 1945 calling it Aviator, One ad from MN as Aviator(first calling out engraving) dated 1946

an ad from Canada dated 1944 and one from NY dated 1945 calling it Warrior. I wonder if it's possible the 1940 and 41 ads off site are of the unengraved Aviator, it's hard to tell. Perhaps 1945 was a transition and the engraved Warrior was rolled over into the Aviator name, adding the engraved case to the name? Circa 1942 to Early 1945 Warrior, late 1945 to 46 and beyond - Aviator (46 called out as engraved Aviator in ads as opposed to previous unengraved?)
The NY Warrior ad seems to confirm a US model name as opposed to a Canadian name for a US watch. By available ads, it looks to me like the engraved Warrior became the Aviator "B" in late 1945 with subtle dial changes.
Just thinking out loud.
My vote is 1942 Warrior
Excellent ad find, Jim!
