Pierre, I believe both versions of the lathe use module 1 gears. And I think they are sold with same set of nylon gears. But I could be wrong about that.?

I have done some single point threading on the lathe. As the difference in pitch between 16tpi and 1.5 mm is pretty small, I never really noticed. Many times I threaded things I didn't have a tap or die for. So I would end up doing both sides. But I am kind of embarrassed to discover it after such a long time.
