Conect lathe stepper motor ID

[Rabs]

I have a conect lathe with no electronics and this motor attached on the x axis:

and an unmarked smaller motor on the cross slide.
I can't find any documentation for the motors on the web. I'm guessing that the 1.8 at the end might indicate current per phase.
Does anyone have one of these lathes and/or data on the motors? I'm trying to specify driver electronics and need to know what drive voltage & current they need.
Many thanks,
Robert
