This Admiral Stamp Has Me Baffled .

Hi guys...This Scott 107 has me wondering what is going on..It is a Scott 107, but can't identify it as a pane or coming from a sheet, because it has 3 straight sides and 1 perfed side...
Its not from a 104a or 107b or 128a or 133...Any thoughts..?

Robert

Why isn't this Scott 128 (the perf 8 coil) with one side trimmed?

Hi paperhistory...I was thinking that, then I ran it through my 3D program to see if all sides had the same consistency..The folds of the edges the angle of the edges made me think again..They were all the same as the pic below shows...BUT, you could be right.

Robert

Robert,
What "3D" application did you use?

Am I loosing it Don..When did you become a moderator..?

I agree with paperhistory, it sure looks like a 128 trimmed while passing through an affixer. The simplest answer is almost always correct, so it seems disproving 128 would be the first step.

So what does your 3D picture show? It means absolutely nothing to me without detailed explanations of what you are trying to show.

Robert,
I became a Mod in July. Which microscope did you use for the image? And what is the file format?
Thanks
Don

I believe the picture is from a scanner, manipulated with the software mentioned in this earlier thread location as Gwyddion.

Wert, I do not know anything about Canadian stamps, but I believe you have either a trimmed stamp ( Maybe by a mechanical postage applier ? ) as paperhistory suggested or could be the end/start of a roll ?

The only way for the app to generate a real 3D image is if the image was generated by a device which understands the Z axis (depth). Scanners typically only generate image file with X and Y axis data. And of course the file has to be saved in a 3D format (i.e. .STL) which contains the Z axis data.

So using a 3D app with a typical flat bed scanner and a normal file image format, if that is what Robert did, would not generate any depth info. It would be able to map a color histogram to make it look like it has depth but this is not the same as a true 3D rendering.

The app Robert mentions can indeed illustrate Z axis depth but the key is in how the image is originally generated and saved. For example, if you had a 3D/surface profile microscope and the file was saved in STL format then the resulting image would indeed be a true 3D representation.

What does the end of roll stamp look like for period coil?

Since the straight edge is on the left... would that be the start of the coil roll?

Don is correct. A true 3D scanner scans real-world objects using one or more cameras to scan the x-y-z coordinates of an object. If a single camera, it rotates around the object as it scans. The image data can be exported into a 3D modelling program. From there, the object can be manipulated inside the software and even exported to a 3D printer. I use professionally 3d programs such as Solidworks, Sketchup and Autodesk 123D Design.

A standard flatbed scanner cannot read depth, and scans the surface (x-y) only. Sure, some software can try to interpret depth based on shadows and a slight slope on the sides of the stamps or other thin objects, but this can generate inaccurate results.

Aside from that, I think Robert's stamp is the start of a coil, or a coil with one cut side.

Good for you Don..you deserve it.



Well John Becker, I wanted to raise the 2 connecting edges at the same time and Gwyddion has the capability to do so..I wanted to see if the edges both curved in sequence to each other..If so, then both edges were cut/created with the same tool cutter/trimmer from the original creator (post office).



Correct partime.



It saves as a PNG format Don (or others is desired)



BeeSee, DONE..I accept that and will forget about trying technology any more to find out answers for questions that people think things are.

Thanks for all your opinions...Robert

Based on the discussions, I agree with oldguy, BeeSee etc etc........I do not have the expertise to do 3-D......having just a hard basic time finding Watemarks on early Denmark stamps (LOL) ! Interesting....I guess we all have our queries

Maybe it is a coil paste up pair that separated into two stamps of which this is one of them. See: http://www.bnaps.org/ore/VanSomeren...ps-Coils.htm

Scott 107 is perf 12. Can't be.
Scott 128, perf 8v. Sure looks to be.
