Becker does not make high vacuum pump, but does say their pumps
operate at 0.4 Torr. So not too bad and certainly good enough for
degassing.

probably non-detergent and I am pretty sure it was a single grade oil

Many of the older piston pumps used straight-weight motor

vaccum site might pin down the answer to this question.
