Vintage 1960's Atlas BS-36 / SW-1 microphone stand adapter Electro Voice Shure

This adapter was originally sold with the BS-36 model Atlas floor stand that utilized the larger boom arm with the 7/8 X 27 thread. It's similar to the Atlas SW-1 adapter but it's larger and won't screw onto a regular stand unless you use an Atlas AD13 adapter with this one shown.
