The devil is in the detail. AKMs aren't AK-47s. People refer to the entire AK family as AK-47, but technically speaking only the first three versions in Soviet usage are proper AK-47s and feature milled parts.
The later mass production model that saw actual widespread use and was exported was the stamped steel AKM, not the more complex AK-47. Not to mention later iterations and foreign production that copy the AKM.
So, no, original Soviet AK-47s are quite rarer than you might suspect.
