Probably much like a Centec vertical head in design. That had similar - hand engraved matched bearings, grease for top and bottom bearings and oil for bevel gears, oil for that was Vitrea 41. They were designed as a slow total loss system as were many old machines. My Centec would run a couple of days before the oil level dropped too low. The casting had an internal dam that the oil was behind and only a small amount splashed onto the spindle and dripped out. In practice it worked well - if it's working - leave it alone, the odd splash of oil is part of the experience.
