US Specialty Perforation, Grill, Design Size, Coil Width Multi-Gauge

US Specialty Precision Multi-Gauge

Has all the features that other multi-gauges do not. Has so many capabilities that it makes other gauges obsolete. A bold claim, I agree but read on and decide for yourself.

The U.S. Specialized Multi-Gauge is the essential tool for any collector interested in U.S. stamps from the Classics through the Liberty Issue of 1954. The gauge contains 10 precision measuring devices beginning with a Specialty Perf Gauge based on the Kiusalas Specialist Gauge. For collectors of the Grilled Issues, there are two useful gauges: the Grill Pattern Gauge, used to determine the grill type of a stamp, and the Grill Size Gauge, which is used to determine the size of the grill. The Parallel Line Millimeter Gauge is used to measure the width or height of coil stamps, as well as the parallel accuracy of coil cuts and edges. For collectors of Flat Press/Rotary Press issues, the Design Size Millimeter Gauge will quickly measure the size of the frame design of these stamps. The Schermack Private Perforation Gauge accurately reflects the vertical height of Schermack Type III perforations. The Large and Small Hole Perf 10 issues of the Liberty Series can easily be distinguished using this measuring device. A Standard Perf Gauge, which measures to the nearest tenth of a perf; a Standard Millimeter Scale and a Cancellation Diameter Gauge are the final three devices on the gauge. It is brand new and quantity dealer inquiries are welcome. Includes a protective slipcover shown in the photograph at the bottom of the page. The back of the slip cover has a summary of the instructions and feature description shown below. You can also download a PDF information sheet here. The slipcover is made from glossy 90 lb. card stock. The multigauge itself is made of durable hydraulically laminated clear polyvinyl acetate plastic and measures 10.4 x 3.9 inches and is 0.014 inches (14mils) thick.

1. Specialty Perforation Gauge, Bureau Issues
is used to determine the perforation measurement of a stamp (number of teeth or holes per two centimeters) Our gauge is a variation based on the Richard Kiusalas Specialty Gauge produced in the mid 1960’s. It has various settings for perforations commonly believed to be the same. Thus, there are three “perf-10” measurements possible, 10-79,10-80, and 10-81. The second set of numbers refers to the spacing between holes in thousandths of an inch. The dots of the gauge also matches the diameter of the pins that cut the perforations. Use the gauge the way you would any ordinary gauge. Make all measurements under 5 - 12X magnification. The match should be exact along the entire length of the side being examined.



2. Standard Analog Perforation Gauge
is used to determine the perforation measurement of a stamp (number of teeth or holes per two centimeters). If all perforations align on the horizontal dots, that's the precise perforation. If the point of alignment falls between the dots, the stamp has a fractional measurement.

3. Grill Pattern Gauge
For United States Issues of 1867 to 1871. Grill Pattern Gauge is used to determine the grill type of a stamp. It is important to understand and determine the correct grill type, as many issues have several grill variants. For example, the 3 cent Washington issue of 1861 (Scott 64 and 65), was printed again in 1867 and can be found with 7 grill variations. The grill classifications can be determined by the size of the grilled pattern, the shape of the grill point and which side of the stamp the apex of the point appears.

4. Go-NoGo Grill Size Gauge
Many of the later grill patterns are faint and can be hard to see. By examining the stamp with a bright light source at an extreme angle, one can use the go-nogo portion of the gauge to determine the correct classification of grill.

5. Cancellation Diameter Gauge
is used to measure the diameter of circles, date stamps, and any other marking or detail, which are traditionally scaled in millimeters. Place the scale over the object of interest until it is centered within the rings. Then read scale. Rings are at 10 mm increments. Major divisions are 1 mm and minor divisions are 0.5 mm.

6. Liberty Issues of 1954
is used to measure and differentiate between the large hole and small hole perforation 10 varieties of this series.


7. Parallel Line Millimeter Gauge
is used for accurately measuring the height or width of coil stamps. It is also useful for verifying the parallel accuracy of coil cuts and edges as well as perforation spacing across perforation rows. This is typically used under 10-30X magnification. Accurate readings require a consistent technique. The edge of the stamp being measured can be placed at the "0" mark of the scale in three different positions: 1. The edge of the design flush with the left side of the "0" marker. 2. The edge of the design flush with the in the center of the "0" marker. 3. The edge of the design flush with the right side of the "0" marker. How one begins, technically makes no difference. What is important is how the final reading is taken. It must be consistent with how the scale was positioned at the start.

8. Go-No Go Design Size Millimeter Gauge
is used for quickly measuring the height and width of a stamps frame design. The gauges line width is 0.10 mm and is helpful for determining the direction and ratio of paper shrinkage if present. It is graduated in 0.25 mm increments for the most common design sizes of the bureau era.

9. Go-No Go Schermack Private Perforation Gauge
Measurements of many Schermack Type III perforations show that horizontal spacing varies considerably. The average horizontal centering is about 20 mm. While their horizontal spacing varies, their vertical dimensions remain fixed.

10. 3. Go-No Go Rotary / Flat Plate Press Gauge
Quickly determines if the stamp was printed using the Flat Plate Press or Vertical /Horizontal Rotary Plate Press. Make all measurements under 5 - 20X magnification. Simply follow the instructions on the gauge. This is typically the 1st approximation and specialists then measure the stamp using the Go-NoGo Design Size Millimeter Gauge. (Gauge Number 8 Above.)


11. 240mm Standard Millimeter Scale
Major divisions are 1 mm and minor divisions are 0.5 mm. As stated earlier, accurate readings require a consistent technique. The edge of the stamp being measured can be placed at the "0" mark of the scale in three different positions: 1. The edge of the design flush with the left side of the "0" marker. 2. The edge of the design flush with the in the center of the "0" marker. 3. The edge of the design flush with the right side of the "0" marker. How one begins, technically makes no difference. What is important is how the final reading is taken. It must be consistent with how the scale was positioned at the start.
