Edwardian Script  Sugerido por donshottype 
Shelley Andante Script  Sugerido por donshottype 

Looks like a custom product.
Compare to Shelley Andante Script

Edited.
In my first version of this post I suggested that the _A_ could have been made by combining the left and right portions of the _M_ in Snell Roundhand. I also floated the idea that Snell Roundhand could be the source of the _y_, edited by pasting the bottom loop from Shelley Script.
This would work but there is an easier way for _A_ and _y_. See next post.

Shelley is close but in some ways Edwardian Script Alt is closer.
Edit the _A_ stripping flourishes.
_y_ as is.
Strip flourishes from _B_ and _P_
Rest of lower case as is except for _o_ which should be edited to look like the _o_ from Shelley.

The result of applying the cuts to Edwardian Script Alt




Looks like an exact match.
