Abstract

573,065. Stamp perforation gauges. RANG, C. P. Oct. 26, 1943, No. 17603. [Class 97 (iii)] [Also in Group XIX] A device for measuring stamp perforations comprises a transparent panel with a series of longitudinal converging lines 1 and lateral lines 2 or graduations whereby when a stamp viewed through the panel is positioned so that the perforations coincide with the lines 1 'the number of perforations can be read off on the lateral edges of the panel. The panel may be mounted in a slide fitted with a magnifying glass.
