As above, if you want to use it for screwcutting, check that the change wheels are there.

they don't have a tripNot necessarily.
If you have an automatic feed trip on the carriage feed they're still incredibly useful:

The DRO actually makes it easier to make use of the stop in that scenario.

I thought that was the feature that had made them such good machines for training establishments.
