Yury Lonchakov resigned from the Russian federal space agency. This patch closely resembles the A-B Emblem version, however it has some subtle differences. It is presumed it was made to take advantage of the large sums of money paid for the A-B Emblem version (> $400).

This version was sold on eBay, sourced from Russia.
