I believe we have the "Windsor"... first applied numbers dial we've seen. Sporting a really different 13 AF that is shaped like a 7 series.. pretty interesting.
Usually these applied numbers are in that transitional time around 1929-1930' ish where the watches will have an either or... curious if it was a choice for the buyer at the jeweler?
* another tell is the curvature of the Case bezel, the subject watch bezel is flat, no curve.
the 'WINDSOR' has a curve to the bezel, accepting a MX type crystal.
I would also venture to say that the case of the subject watch is slightly narrower than the case of the 'WINDSOR'
