Hello Gary-

Thanks for your reply--Did you just offer to make the spring for me Smile

?

Actually I tried to make the spring located at 7 o'clock but found that I given the length I could not get the tensile just right for correct hammer
operation-too strong button was over powered, to weak and return was partial-wound up finding one. I suspect there will be a tensile issue
on this one as well. For me proper running of chronographs always seems to be a matter of spring pressures and eccentric screw positions.

Still hoping to find one!
