I guess 'old' might be the most operative word.
T but Mitutoyo (US and Japan) seem to be the leader in metrology these days and now even make a sub-micron (μm) micrometer.
I guess my OP was expressing surprise, that given the position of German hand tools (Knipex, NWS etc), their measuring instruments don't seem to occupy the same place.
Sorry, i don't see Mitutoyo as the leader......I see it as Federal/Mahr & Starrett being out in front with "normal" toolroom accuracies in precision metrology equipment (accurate to ranges up to and beyond .0001).
As for the Germans, yes they make very nice tools, but I see most precision tools were made predominantly in New England over the past 150 years. look at where most precision tool makers were located:
Starrett ~ Athol, Mass
Brown & Sharpe ~ Providence (later North Kingston), RI
Federal ~ Providence, RI
Pratt & Whitney ~Bloomfield, CT
Ames ~ Waltham, Mass
Take it a step further and go back about 100+ years ago and one of the most precise items being made was firearms. Look at where a majority of these companies were made: New England and New York State. Why? Because of the high skill labor force. Yes, Holland and Holland and JP Sauer were made outside the US, but look at where these companies were made: Marlin, Savage, Winchester, Ruger, Remington, Ithaca, Colt, S&W, Stevens, Richardson, Spencer, Sharps, Henry, etc.
I see Pratt & Whitney metrology equipment as being probably some of the most accurate equipment out there. Corning also make some very precise laser equipment, such as their Flatmaster.
Go into a shop that has clearance tolerances to millionths and beyond you will see a lot more brands than you mentioned.
