A member of the Russian site, "SAMMLER.ru" noted there is an 1899 "Firearms and edged weapons of E. Schmachtenberg, Moscow" catalog.

I have also found a 1901 Passport for Carl Schmachtenberg, "book-keeper", born April 9, 1851 in Solingen, living in the United States from 1880 to 1898, and was living in Moscow, Russia in 1898. Since this person was living in the U.S. 1880 to 1898, he was probably not C. E. Schmachtenberg.

I have not downloaded the .pdf file of the 1899 catalog and it may not be safe to do so. I would very much like to see what is in the 1899 catalog.

I don't know if these records have anything to do with "C. E. Schmachtenberg, Solingen", but the fact that two Russian swords and one Russian dagger are marked with the arched "C. E. Schmachtenberg, Solingen" mark, makes these records very interesting.
