The old grease from the 1910's was petrified and had to be chiseled off. Soaking everything in PCS-1000 parts cleaner helped tremendously. When I re-assembled it for the final time I used Tribol Molybdenum grease. This stuff is amazing! Even if it wipes off or goes dry the Molybdenum gets into the crystalline structure of the metals and continues to provide lubrication.
For your enjoyment a little Harry James and his Orchestra!
What it really needs is a genuine Victor Exhibition reproducer. The Tip Top that came with it is deteriorating so badly that I dare not remove the screws to replace the seals. The potmetal is cracked and falling apart. The search is on.
