I also have one of these mills, except that I'm in Australia, so I got
it locally. It works very well.

Not really. It is actually a metric machine. The leadscrews are 1.5mm
pitch & the dials are divided into 125 divisions, giving 0.02mm. They
are numbered 0 to 14 each 5 divisions.

I was going to convert this to CNC of course, but haven't started yet.
