The case has the shield symbol (1939?) and the movement has an arrow (1937).
I tend to Lady Bulova, Barbara has at least according advert wider case

I am certain I'm not going to tell Barbara that she has a wider case! ; )
I don't think the Barbara has the same lug area, it is more open around the lugs without the lower protrusions. Lady Bulova is a good match; and the date should be 1937 based on the '7' and arrow movement stamp. I forget what the shield on the case means, but it does not indicate the date.
