“That's the reason even though that snare is 40 or 50 years old,it still maintains a near perfect finish.”

This⬆️ Exactly, why would you spend money on an original finish and re-chrome a near perfect finish because of some marks that are part of it’s history. I would also be leary of today’s quality of chrome compared to 40-50 years ago.

Whatever you choose good luck and either way it’s a beauty.
