10AE AAA 21j, believe there was a long discussion about this a lil while back
IMO, the only thing that is obvious here is that you are making assumption after assumption and confusing them with actual fact.
Measurements would constitute actual facts and something worth discussing.
We have one ad that shows one variant--the "A"--of this style of Lone Eagle. We have no information regarding what the Lone Eagle without a variant designation, or the "B", or the "C", etc., etc., would look like. It is quite possible, perhaps even likely, that one of them was designed for a leather band and would not have the lug extensions.
The Ambassador has a different size case and takes a different crystal. Both sets of dimensions are needed to know what this watch is.
P.S. Question: Have we ever seen this style of Ambassador with an engraved bezel?

Too big for a LE crystal, so that would put it as an Ambassador, or unknown with the engraving along the sides

Looks like someone had fun cleaning the dial...
