These are chuck jaws I found in the cabinet next to where dad has his South Bend 9A. He sold the lathe about 15 years ago, but must have forgotten to put these in with the tooling.
These don't fit any other chucks he had, so my guess is that they fit the chuck that came with the lathe.
They are a set of 1, 2 and 3. The 1 and 3 are marked C82 and the 2 is marked R51, but they all appear to be a set.
The jaws are 2" long, 0.543" wide. The groove is 0.244" tall and about 0.300" wide (it is wider at one end than the other due to wear). The teeth match up with my 4tpi thread gauge.
If you need any other measurements to see if it fits yours, let me know.
