Vintage RCA AD-1 microphone stand adapter 5/8 X 27 to RCA thread 77DX BK5A 44BX and RCA MA2305 Lot

RCA AD-1 microphone connector / adapter used primarily on RCA model microphones.  RCA used a much wider thread pattern on many of their mics and stands so it was essential to have these adapters to mount an RCA microphone on a standard 5/8 X 27 thread desk or floor stand.  . As you can see in pic the original adapters has some cosmetic wear and scratches. The outer ridges are great and this will fit and hold just fine. These connectors are not always easy to come by. Also included with the AD-1 is the chrome RCA MA2305 stand adapter. Set of two as shown in photos.
