Cheers everyone,
I was wondering if any of you studio veterans recognize what brand mic boom they are using in this photo?

I'm especially interested in that gray colored, swivel adapter that is attached to the end of the boom arm holding the Neumann, . .anyone know what this this adapter is called? Thanks fellas

Wow, cool photo.
Those stands look like the old Starbird Microphone booms, that were originally manufactured by George Starbird. But, I could be wrong. . .
