Evidence that the early numbered Bulovas were of the Lady/Hudson Maxim w/watch line
The idea that the early Bulova wrist watches belonged to the Lady/Hudson Maxim lines is not a new one, it has been discussed on this and other sites for quite some time.
Until recently, this has stayed in the "ideas" department, as there was little proof to back it up.
With the finding of actual Lady/Hudson Maxim adverts dating from mid-1921 right up until 1924, we have a basis for some debate and some of the ads even back up the above "idea".
