It's an old RCA ribbon mic. It has a square brownish/charcoalish body. The RCA logo isn't the big red round one, it's square. The ribbon inside goes over the top and down the back. It seems to be a figure eight pattern but also has three switch positions (patterns? impedance? low cut? wha?). When I switch the positions I can hear the low end getting thinner, but that could be from changing patterns or low cut. The cable is attached and the mic stand collar is directly attached to the mic. In other words, it doesn't have the U bar cradle that you see with the big cylindrical suppository shaped 77DX's or the square 44BX's. It is shaped more similarly to a 44BX, but smaller. A friend is letting me try it out (possibly buy). The only thing he knows about it is that he got it from a military guy at Los Alamos NM (where they built the bomb). A model number and dollar value would be very helpful.
