I have a pair of "Shure" Omni-directional, dynamic microphones. The Radio Shack p/n is: 33-1070D. Is this a private label of an existing Shure model, and if so, which is your model number? Thank you.
There is no equivalent model in the standard Shure line. The 33-1070D was designed to Radio Shack specifications. The closest model in the Shure line is the VP64, however it is not identical in performance.
