This is an interesting one - Primo EM50 electret; sold as the CP-3 12mm 'pinpont omni' for the Nakamichi mics, using a special adapter. Nak probably had theirs made to spec, or at least carefully culled (and they were black).

I've bought several of these over the years as the capsule on Primo EM4052PM measurement mics. Amazingly they shipped with the actual B&K freq response readout sheet.

at the request of @rock soderstrom I post the different capsules in my possession as well as my comments...

first is a "generic" Ali Express simple diaph. which is not well balanced > too much highs and high-mids > not interesting

I note that nobody never posts (or talk about) Audio Technica capsules : a reason for that ? AT mics are not garbage and some ref. like AT4050 are great mics
Does anybody knows about AT4033 capsule ? It's a ref. Mic for its price
