Here are multiple links to Anosov's "On Bulat" published in French in the "Annuaire du Journal des Mines de Russie" 1841, St. Petersbourg.

Haven't read it yet but will do shortly.
The original "On the Bulat", was published in the Russian Gorny Journal in 1841 and is easily available online as Mahratt suggested. I'm sure the later German version can also be found.
Maybe that will put to rest what Anosov did and didn't do. Don't expect pictures though. These are poor scans of an 1841 journal.
