i really don't know!!!
but it coul'd be a russion replica of maybee the sennheiser, or similar
i have a friend in london who has several replicas of top notch mics made during the communist era in russia and they look all slighltly different then their original counterparts, but sounding AMAZING, better say without any audible difference to the original!!!
whereby there have been tons of different replicas of the same mic made in russia during the C era (some are extremely good, some of them are shite!), maybee you have one of those lucky dips, like my friend... he has e.g. a U87, C414, etc. for next to nothing sounding just like the Original, and well crafted too...
