I have a friend who lives in another state that has a couple of AK's I am trying to ID. He says that he bought them at a gunshow in the late 80's. They are in brown cardboard boxes. They are both underfolders. They are sealed in red plastic bags in the folded position. He says they are covered in cosmoline. I know this isn't alot of info, but it is all that I have. Is that enough info for anyone to give me an idea of what rifles these may be?? I am an AR guy and I don't know alot about AK's. Thanks in advance for your help.
