Hi Peter,
try again! The part number for the K 87 capsule is 053224, and it certainly is still available. It may not be in stock locally, but can be ordered from the factory.
The pictures show your vintage U 87 in remarkably good and original condition. The capsule may have been replaced previously, It does not look bad or contaminated, but appears to have a hole just below the center terminal. You may try to have it dried and cleaned by a qualified studio microphone specialist, and if that does not cure it, by all means, replace the capsule. This specimen looks like it is worth it!
