Size And Orientation Of Washington/Franklin Watermarks

Please consider this image of a Scott U.S. 428:



The image shows the same stamp, wet and dry.

If this one specimen is any indication, the height of the single-line watermark is approximately 40% of the height of the stamp itself. There is crude numeral 5 penciled on the center of the stamp. But to my point, there appears to be the watermark of an upside-down letter "U" in the lower left of the image. This begs a couple of questions:

1. Is this watermark orientation unremarkable? Could one find a perpendicular orientation... or diagonal?

2. Is the scale of watermark consistent across all panes and all denominations of an issue?

I get the impression that U.S. double-line watermarks were scaled somewhat larger than their single-line brethren.

Your thoughts, please.

BF,
Many pages of watermark information here http://stampsmarter.com/learning/Ma...ermarks.html

There is also a 'Pop-up Watermark Tool' which shows you the various orientations and possible locations of the watermarks. Note that it is possible for some stamp to have almost no watermark showing even though they came from a watermarked sheet.



Don

That especially happens with single line watermarks.

Don,

Very cool tool. One of the many "tires" I had yet to kick on the stampsmarter platform.

So is the diagonal orientation idea tenable?

"That crude 5" is actually a S to indicate single line watermark.

Est quod id est.
