Check your PMs, I gave details there.
Yep, it's a nice mic, no longer made (I'm pretty sure), but not your garden variety tube mic. It's not an LD (more like a medium diaphragm), and it pre-dates the current crop of low cost Chinese tube mics (as well as the Solidtube, 4060, etc.) so it was only competing with the "big guys" when it was designed - and it wasn't trying to emulate any discontinued "classics" (U47, C12, ELAM251, U67 etc.etc.). Works well on a lot of male vocalists & surprisingly good on piano.
