Vielleicht für den einen oder anderen interessant der sein Wappen in Russland registrieren möchte.
It was a pleasure to receive your request.
However the situation is complicated.
There are the Federal heraldic authority in Russia
(the Heraldry Council) as well as several provincial
commissions but all of them temporarily (!) do not
deal with foreigners' arms.
There is an alternative option of a respectable
private registration with the Guild of Heraldic
Artists of Russia; the Guild's attention is also
concentrated on Russian heraldry (broadly, or
post-imperially, understood) but currently it starts
keeping a record of "guest coats of arms" (that is,
"Russified" arms of non-Russian armigers, edited
as if the armigers wish to bear them in Russia).
The Russian heraldic system is relatively
restrictive in many aspects.
For example, certain kinds of heraldic helmets
are reserved for nobles in Russia, although the
same helmets are widely borne by commoners
in various European countries.
