Brent, at best we would only be able to identify the windscreen, not the microphone that's in it. You're right, the windscreen is of a type that Schoeps has manufactured for decades. digifish_music's photo is also of a Schoeps, or an exceedingly good imitation.
However, in the 1950s and early 60s Schoeps manufactured accessories (including windscreens and table stands, etc.) for Telefunken, Philips, Siemens, and even (I kid you not) Neumann--all of whom sold them under their own brand names. Or in one case, the "M 280 N" (variant of the KM 84), Telefunken was selling Neumann microphones with Schoeps windscreens and other accessories under Telefunken's brand name.
So it's entirely possible that the microphones are Schoeps M 221 Bs--but it is also entirely possible that they are AKGs, Neumanns or even (gasp) something else that just happened to be the right shape and size.
Yes, sadly, it's true--no one in this forum could possibly know this from their own experience, but--recording engineers sometimes ... improvise a little. It's a huge scandal, of course, so please don't tell anyone that you heard this from me.
