Snap test requires some experience, instead ID paper type by perf tips and backlighting.
Perf Tips
The stamp shown above is soft paper; it can be identified by the look of the perforation
tips.
Soft paper perf tips look fibrous, a bit ragged. Hard paper perf tips are typically clean cut, crisp looking.
Backlighting
See this link to understand how paper types appear when viewed with a strong backlight

Thank you,I read the article ...for backlighting UV I don't have possibility.
Two things I do:I don't have experience but I have a stamp with soft porous paper.
I post for comparation the Scott 206 and 205C (that I think).For me is not any difference(after "snap test" and "perf tips").With back white light the structure of paper,for me,it's the same.What you think?
With the help of "stampsmarter" I identified as Scott # 206 (reengraved design-shading in the Ornament above US).
This stamp was printed only of soft porous paper?(I asking because after "snap test" according my ear the result was "hard paper")
