Adding further to this the following observations:
The two watches entered by Geoff (White and Yellow set), has a sub-second design the same as the Lone Eagle adverts.
The other two examples we have show the Bernard sub-second design.
The notion that we have no 1933 adverts or watch examples of the known LE's is correct.
So maybe just maybe what we are seeing here is a Bobbee originally theorised, and that is the initial release of a new LE model around September 1933, then the timely withdrawal by Bulova due to the kidnappering event, and then the subsequent rebadged release of the watch as the Bernard.
