I’ve got a Simpson micro ohm meter, but are finding the same resistor
measured on two different ranges, gives different values. The differences
are not huge, but suggest calibration may be required.

That's just hanging for me - I can't connect to the site, either from m
iPhone or Sun workstation. I managed to find the user manual okay, but not
the service manual.

It seems to be going via kasperksy for me. Maybe they have an infection ?

The wayback machine has access to most of the downloads (

can only see a 444 ops manual there, not service.
