Sheaffer used a dial indicator nib gauge for measuring nib sizes. The nib was inserted into the gauge, and the size read off of the dial. A given size being nibs that fell within a given range. What is listed below were the ranges given on a gauge that I saw in the Sheaffer service center prior to being closed in March 2008.

Measurements are in thousandths of an inch.  MM in bold type.

XXF = 0.010 - 0.013 =  0.254mm - 0.33mm
XF = 0.013 - 0.018 = 0.33mm  -0.46mm   
F = 0.018 - 0.025 = 0.46mm - 0.63mm
M = 0.025 - 0.031 = 0.63mm - 0.79mm
Broad* = 0.031 - 0.050 = 0.79mm - 1.27mm
Stub = 0.038 - 0.050 = 0.97mm -  1.27mm

*there was some overlap on the gauge. The broad nib is finer than the stub nib at the low end of its range, while the high ends match.

 

updated 5/16/19 to show conversion to metric units.  Sheaffer's original dimensions were in thousandths of an inch, but most nib sizes today are graded in mm, so this makes comparison to current standards easier.

That is very interesting. The variation between sizes as normal, is larger than I expected.
Was Sheaffer and Parker about the same width in nib size?
I don't seem to hear of any wars about it, over on General.

There are verbal wars going today, as to what is medium or fine or EF; involving one company that is a touch wider than "normal" (That uses dry inks) and another that is a bit narrower than "normal"(That uses wet inks). There for each meet in the middle.

Was/is Sheaffer inks, wet, dry or in the middle?

The real problem is not one company is larger or narrower than the other but the users are using the wrong inks and end up comparing cherries to pineapples.
Both have their place on a cocktail stick in a proper drink.

German vintage '50-70 semi-flex stubs and those in oblique give the real thing in On Demand line variation. Modern Oblique is a waste of money for a shadow of line variation. Being too lazy to Hunt for affordable vintage oblique pens, lets you 'hunt' for line variation instead of having it.
