Here are detailed  High Resolution Picture: https://goo.gl/juFR4zObservations:1. It have a hardly observed dent (I didn't observed it until an ebay user observed in High Resolution Pictures) 2. I changed the original tube which is a low quality tube with lot of HIS. I put a high quality one and the difference was huge.  Higher dynamic ratio and also less HIS.Not used in the last 4 years (because I don't activate in music industry) but it's stored in proper condition. Non smoker and it was never stored in unproper  environment. I'm not in hurry to sell it but since I don't use it I'm willing to sell it for a right price. Please don't send me indecent offers because you lose your time and my time. I'm only open to drop symbolic few bucks.
The Gefell UM92.1S is a ‘vintage’ large-diaphragm multi-pattern tube microphone.  It is equipped with the original M7 capsule.  This pressure gradient transducer features a dual-membrane, gold evaporated PVC capsule that is still hand-made in the Gefell factory following the 75-year tradition.  The Gefell UM92.1S is the choice for those that want the true sound and character of the original Neumann-Gefell UM57 with the added benefit of improved reliability and lower noise.  The UM92 exhibits high sensitivity, excellent signal-to-noise ratio and it has the full sound, tube warmth, and character that are favored by singers and soloists. Design Features
The Gefell UM92.1S is a multi-pattern microphone with switchable back-diaphragm voltage on the power supply for choice of figure-eight, cardioid and omni-directional patterns.  It is also available in a cardioid-only version called the M92.1S. As with all Gefell microphones, mechanical and electrical attributes have been optimized for performance. Careful attention to reducing ‘vortex’ around the mic and capsule is achieved by mounting the M7 capsule on triangulated pedestal.  This has the benefit of directing unwanted reflections away from the capsule, reducing comb-filtering and phase disturbance.  The smaller housing advantages the user with greater freedom to place the mic in tighter spots while also reducing particle pressure refraction or what is also known as the vortex around the mic. Following tradition, a natural presence rise provides added clarity and detail ‘on-axis’, while the ‘off-axis’ transition is both smooth and musical.  The habitual low-frequency proximity effect provides a warm bottom end that is enhanced as the source is brought closer to the diaphragm. The UM92’s internal low-noise vacuum-tube amplifier features a ‘time proven’ design that employs a high-mu triode valve that has been selected for its warm sonic characteristics and the natural even-order overtones that are only possible from a tube.  For long cable runs, a filament voltage stabilizer is built into the microphone that allows distances of up to 100 meters (328feet) without fluctuation.
