Hello to all Stamp maniacs over here


Welcome Loannes,
Yes indeed, some Russian stamps whilst not having "fugitive"
ink, do lose their pigments when soaked.
I do not like gum on my stamps, and wash them where possible
and found Russian stamps (mid 70's perhaps?) partially lost
their pigments, so I gave up soaking any Russian stamps.
To the purist they are damaged, but I wouldn't throw them away.
So you are left with a quandry, some russian stamps have thick yellow gum that cracks readily if not kept in good conditions, and
a loss of pigment if you soak them.
I am not a specialist, I do wonder if Russian gum is different
on the initially produced examples and those used as CTO's.
