Vintage 1950's Electro Voice 911 crystal microphone w period Atlas DS5 stand 611
Pic # 2 is from an old 1950's E.V catalog showing this very model. Before the 611 and 911 models there was only the 610 and 910 model. These were the forerunner to the later 611 and 911 mics that were sold from the 1950's to 1960's.
