Greetings, I'm the caretaker of what I believe is a pre 1920 South Bend 34-C & I'd like to affix a different chuck. Before I remove this chuck, I was hoping to learn more about what thread size & pitch the 34C originally came with, but I'm having some difficulty finding info on models this old.
Any info or assistance would be greatly appreciated.
