WRT to compatibility, I would wonder whether there might be other compounds in the original blend or even the base itself that might not be compatible with those of more modern greases, even though they do contain MoS2. Perhaps better to err on the side of caution.

As for the original recipe, I worked at the Avanti plant for a few years after it moved to Youngstown, and they had many copies of blueprint copies of the original engineering drawings from Studebaker, as well as original drawings from Avanti Motor Company (nothing on Packard, though). Yet, I noticed that when a component could not be described by physical dimension, a drawing was still issued - one that included text details or a refernce to some other internal or supplier document.

Has anyone ever inquired about the P/N 474028 grease with the Studebaker museum in So. Bend? They're not engineers, but the museum received a donation of many Packard engineering drawings some years ago.

Alternatively, would it be possible to take a sample of grease form an existing, low mileage, original compensator planetary, have it analyzed somewhere?
