The ones I seen were marked both. I had to look at the Remington O/U for $400, but it became clear why it was so cheap when I seen BAIKAL stamped on it. IIRC, it is sold under Sportsmans brand, or something like that.
Wasn't a bad looking gun either. Another one to look at is the Khan O/U imported by Century. I almost walked out with a .410 the other day, lighest gun I have ever felt and a quite beautiful stock.
