I have a South Bend heavy 10 lathe. I have figured out the catalog number CLC 187 YB, with the exception of the second C. On the South Bend website all of the catalog numbers for 10" are CL, with no listing for CLC. I sent for and received the serial number card. My question what does the second C stand for ? Have to laugh as it is driving a little crazier than I already am. Serial number is 8363 RKX 14 and catalog # CLC 187 YB.
