This is a BETA 52, the predecessor to the current BETA 52A. The differences between the old and new models are the shape of the angle adjustment screw and the material of the rubber O-ring. O-rings that are damaged will not allow the angle to be fixed, but this one has had the O-ring replaced and can be locked. Operation has been confirmed. Included accessories are a 3/8 adapter and a SHURE microphone pouch (worn).
