2002-07-11 There is a possibility that such parts when made in metric factories, in metric countries, using standard metric steel sizes, may in fact rationalise the 1 inch to 25 mm and the 1.12 inch to 28 mm. The differences are not noticed and even if they were, they can always be excused away as the inch sizes are not practical in a metric country, or the old sizes are just trade names that have stuck around even though the construction long ago went metric.
And it may in fact be the same situation as a floppy disk. Made to 90 mm width, but called a 3.5. The only way to tell if it is true metric or true FFU is to get out a precision measuring instrument and measure a sample of the parts.
