You are getting a vintage microphone made by Shure Brothers. Model CR-81 with controlled reluctance. Includes cable and plug. I plugged it into a small amp and it works. The Chicago address on the back indicates this microphone was made 1955 or earlier. (Shure moved to Evanston, IL in 1956.) So it was made before 1956. Please see all pictures and ask any questions needed to make a bid as we do not accept returns or refunds. Thanks.
