The Pyorremyersky was NOT a copy of the Me-109, the only similarity between the two was the use of the same engine, the Daimler-Benz DB-605.
"The Pyorremyrsky could outclimb the Bf 109G-6 and was more manoeuvrable..."
Although that was true, the first prototype didn't fly until after WW-II was over, so the results were purely academic. In any case, with the end of the war the manufacturing source for the DB-605 engines dried up as well, so there was no possible way that this fighter could ever have been produced in quantity.
