Abridqement A measuring plate (10) supports successive rows of perforation fingers (24i-k) on its upper side, the spacing and diameter of which respectively correspond to the perforations of a postage stamp. By laying the postage stamp on a row of perforation fingers (22i), the conformity of the postage stamp perforations and measuring perforations can be checked in a tactile manner. The measuring plate(10)is connected by way of a hinge (30 to 34) to a trough-like lid member (12), which can be used for checking water-marks. The measuring plate (10) and lid member (12) together form a flat carrying case for postage stamps. (Figure 1). |
