Tom Senior spindle bearing lubrication

[old martParticipant @oldmart]

In the TS light vertical mill, I am unsure how the taper rollers in the spindle are lubricated, oil or grease?

According to the manual I have for M1 and Major:

Slides, Feedscrews, General Lubrication – Shell Vitrea Oil 33 / Castrol Perfecto NN / BP Energol HP30

Gearbox – Shell Vitrea Oil 37 / Castrol Perfecto RR / BP Energol HP40

Spindle Bearings – Shell Alvania Oil 3 / Castrol Spheerol A.P.3 / BP Energrease L.S. 3

Vertical Head, Rotary Table – Shell Alvania Oil 2 / Castrol Spheerol A.P.3 / BP Energrease L.S. 3

I was confused because the sectioned drawing of an early S-Spindle I have shows an oil port for the quill with nothing to stop oil getting into the spindle bearings at the same time.
