OK.
The whole "Russian Purdey" thing is only a peculiar Russian way of saying something is the best in Russia. It's supposed to mean "TSKIB in Russia has the same standing as Purdey in the world", but somehow gets to mean that TSKIB is as good as Purdey. Anything could be called by this pattern. ZiL (the ugly limos the Soviet govt. used to ride in) - "Russian Rolls-Royce". A beauty queen could be called "Russian Marilyn Monroe", a rock performer - "Russian Elvis". Matzka is being called now and again the "Russian Purdey" too.
