Galena Cast Crystal for Philmore or Whisker Crystal Radio Diode with Threads

Description

These Cast Crystals Have a Threaded insert. This is a significant advantage for the Do It Yourselfer that is constructing their own Crystal Radio Detector stand since you only need a screw to secure it to the base of your stand instead any metal clips. While these have a threaded insert, the threaded insert is not needed for many of the older style Philmore Stands and just doesn't need to be used.
