Hi, I’m rebuilding a 1946 Stinson 108 and I bought a beautiful CDIA for it that needs some TLC. I have found a new balance wheel to replace the old one. The top (photo) balance wheel end stone is cracked which, I think, slowly cut the pivot down to nothing. I also found one mainspring is broken which caused the balance amplitude to vary and sometimes stop. If anyone could help with finding parts or point me in the right direction, it would be much appreciated. Thanks Marcus.
