How are beef cuts labeled in Russian?
The Russian Wikipedia article on Beef has several diagrams - a current one in the main section apparently originally derived from the German wikipedia, and two others from older Russian sources.

I was also able to find another site with another diagram, and translations of some of the cuts into English, which is helpful because the names are difficult to translate to similar English cuts via Google Translate, which simply gives anatomical terms for many of them.

Here is an article from the Moscow Times discussing the subject, largely from the perspective of someone who only knows the American name for the cut they are looking for.
