I was reading the 1919 Hendey manual and, where it mentions metric calibrated machines, it specifies that Hendey lathes could cut both "French" and "International" metric threads. I'm wondering what was different about the French threads. Thus far, the internet has been useless in deciphering this...which doesn't surprise me.
How do you edit a title? That is supposed to be "French" metric!
