One of the American Eagle range, which letter I don't know, can't find an exact match in the adverts although sure I have seen it in one somewhere. Band is great too. Looks to have never been worn.
Agreed - 1940 Bulova American Eagle "F"
Agreed - 1940 Bulova American Eagle "F"
Now thinking it's the "B" (non engraved version).
Yes I agree with Stephen based on the partial pricelist we now have and the ads. The "B" is fluted with the white dial and by the close up of the ad "F" looks like engraved fluted with the white dial but it isn't 100% clear.
1940 Bulova American Eagle "B"
Agreed, good detective work folks!. "F" is engraved. "B" is plain sides of crystal. I'm changing my vote to
1939 American Eagle "B"
Agreed, based on these new adverts it's a 1939 American Eagle "B"
