Bulova 11AFC M1 (compatible) mainspring

Hello,

Can anyone find which mainsprings are compatible to the 11AFC?
I can't find this mainspring in the catalog of interchangeable parts I have...

Thanks in advance

Regards
Florian

Same as the 11AF, but there are no dimensions listed for the spring. Worst case scenario, you measure the spring and get one with the same specs. You need Width, Thickness, and Length. To find one in a bunch of old stock springs, you may need to convert your measurements to Dennison. 

Alternatively, Mat Supply Houses like Borel and Cas-Ker in the US likely have the spring listed and alternatives as well. In the UK, it will be Cousins.
