Balance Staff for a Bulova 13AT‏

I hope ya'll can help me since I seem to have found a watch with a rather rare movement.  I have a 1932 Bulova Jump Hour that needs a new balance staff.  It has 13AT movement.  A balance staff from the 10AC, 10AT, 13AB, 13AC, 13AL, or 13AN would work.  There maybe other movements/balance staffs that would work in this watch, I'm not sure.  Below is a picture and relevant info of the type of watch I have.  Thank you very much with your help in this matter.

If anyone can help me with the right part I would much appreciate it. 

Respectfully,
