Salvaged balances and hairsprings. I have 3 good balances with pivots in good condition (one is missing
a roller jewel). The hairsprings that are used will have to be checked for trueness, and vibrated to ensure
that they match the balance.
I also have 4 hairsprings (see above). I will pick the 2 springs that need the least work:
1- good condition, although the collet is out of flat:
2- Seems to be in good condition, but will check for trueness, although it is a little smaller than the others,
so I have to verify.
3- The last 2 coils are non-concentric and bent.
