You are bidding on a Grundig GDSM 202 Stereo Microphone.  This is a high quality microphone, as each element is equivalent to a Sennheiser MD408.  It comes with the original case.  The previous owner has built a heavy stand for the mike from brass.  The elements can be separated for greater stereo effect.  They have long cords with 4-pin plugs.  They should be great for your use.
