How Can This Watermark Detector for stamps help you with your stamps?

The SAFE Signoscope is especially useful for finding watermarks which are very hard to see with lighter fluid, especially all European Stamps and British Stamps with their various crown and initial watermarks. It works very efficiently with engraved stamps, such as the 1950 posthorn stamps of Germany. As to the U.S. Single and Double Line Watermarks, keep in mind that if there is only a little “dash” of the “U, S or P” left at the corner of the stamp or in the perforation of the stamp, this is ALL you are going to see.

The Signoscope can ONLY show you what is THERE, not more. Thus, this little “dash” will not be easy to distinguish, because you will also see the fiber of the paper together with any kind of repairs or thins of the stamp. However, if more of the “U, S or P” is on the stamp, the watermark will be clearly visible, especially when using the above transparent vinyl spacers, shiny side UP.

For checking any other foreign stamps we recommend first looking up the picture of the watermark in a catalog before putting the stamp in the SAFE Signoscope. This way you know exactly what you are looking for. Just remember, you will be seeing a negative Image of the watermark in question.

Also keep in mind: You do NOT always see the complete picture of the watermark as shown in a catalog. Sometimes only part of that picture is visible on a stamp. It is very easy to take a picture of the watermark with the help of the SAFE Signoscope and an instant camera with black/white film. The light sensitivity can be adjusted with the Contrast Adjuster of the SAFE Signoscope.
