Abstract
Abstract An indicating member for an instrument comprising a thin perforated metallic element and a translucent film laminated to the metallic element and arranged to overlay the perforations so that light from a source behind the metallic element transilluminates the translucent film through the perforations in the metallic element. The indicating member may be in the form of an elongated tape for a vertical scale indicator or in the form of a dial for a pointer-type instrument.
