I just bought an unissued Bulgarian Makarov. I have a question. Can I find out when my pistol was made by the serial number??? The number is KT 24 xxxx. I know that it was made in Bulgaria due to the "circle 10" mark on the frame. I just want to know when!!!!! I have posted this everywhere I can think of, including makarov.com. I have yet to get a response. I have even e-mailed Dr. Karl. Please help me!!!! Even the news that there is no way to find out would be helpfull, although I can't imagine that being the case.
