The picture tells me that the amount of loss of gold, and therefore increase in noise, may still be borderline acceptable. I would try it! If the capsule is noisy or lacks frequency balance, buy a new or used genuine Neumann K49/47.
But before you buy new, inquire with Neumann, which of the capsule options, K47fet, K47 or K49, are currently the cheapest; that has changed-unexplainably and illogically-through the decades, and, no matter what others may say, I have never found an audible performance difference between the supposed "super-matched" K49, the standard K47, and the single-side use K47fet. Neumann's manufacturing tolerances are that tight.
