I have a new to me lathe, a 70's Colchester-Clausing VS13. The manual
specifies Shell Tellus 37 oil for the headstock reservoir and Shell
Tonna T68 for the apron. I think i can put Vactra 2 into the apron and
be compatible, but what works for the headstock? And further it came
with no center for the spindle. It has D1-4 camlock. What is the
internal taper, Morse 5 ? Manual does not specify.

thanks
