As an experiment, I post the scan of the first, as far as I know, Russian privileges on the counting machine (
Journal of Manufactures and Trade, 1845 No. 10-12 ).
Zelik Slonimsky and his arithmetic machine are well known to computer technology historians, a description of the device is contained in the special literature, but the privilege itself has not been published on the Web - at least I could not find it.

If the post is approved, the publication of Russian privileges on computing devices will continue, otherwise terminated.
