I take it that the now internationally accepted is close to the post 1900 standard. This I take it means that those with lathes made in the early 1900 will not (from this) have trouble cutting threads to the current American or imperial standards?

I believe the difference amounts to about an eighth of an inch per mile -- of interest to long-distance surveyors, but few others.
