Peter Warlock Glass Penetration frame
A solid 9iece of thick glass is placed in a window type frame. It fills the window frame completely. Two wooden panels are slid into place on both sides of the window frame.
Amazingly a needle or other pointed object can be thrust through the holes on either side of the panel. Yard can even be threaded through it. You will need a knitting needle or rod to penetrate the glass. In very good used condition. It works perfectly. We will send generic instructions. Circa 1950 and the size is 12 by 12 inches.
