That is a great eaxample of a beautiful razor that has had a patina develop from many decades of love and care. The pitting and black rust on the other hand comes from long term neglect. The neglect should be repaired and the well loved razor needs to be conserved and the love continued. Know the difference before you start. If you polish a true patina it will take longer than I have on this planet to come back.
Also,
Great job on conservation Mike.
