Mainspring for a 15 Jewel10A Movement

I am looking for a mainspring for a 15 jewel10A movement. Is 10AA the only compatible spring. And will a non Bulova Swiss mainsprings work and how would I cross match that?  

Thank you in advance.

Gerard,

I now have the largest collection of Bulova parts ever and probably have the main spring you need. I will check for it this afternoon later and PM you.

I have a used 10A and a used 10AA main spring complete in their barrels. Which do you want??

PM me and we can talk about working something out.
