Trying to find the replacement for this dual coil balance. It has a 6 or 9 stampted on it but the dual balances I see start at 11. Any advice?

Thanks for posting! The coil springs look to be in good condition, it appears that only your shoe is broken. With that in mind, I recommend our 15-180. This should work well for you.
