The gauge used by the Scott editorial staff to perf stamps for the Scott Catalog has been improved. Not only is the new Multi-Gauge graduated in tenths, each division is marked by thin lines to assist collectors in gauging stamps to the tenth. The Multi-Gauge is a perforation gauge, cancellation gauge, zero-center ruler and millimeter ruler in one user-friendly instrument. It is also great for measuring multiples and stamps on cover! Transparent gauge measures in millimeters, centimeters and inches.
