Well, I'm no expert, and I've only seen a few Chinese, Russian, and Yugos so I can't comment on Romanian variants or 'others'.
Looks to be a Russian. Trigger guard appears milled, bayonet is the Russian pattern, sling swivel is in the Russian position. Stock is about the ugliest I've seen (no offense if it's a home job...), never seen one that dark personally.
Interesting 'do-dad' in front of the trigger guard-aftermarket someting or other?
Now, we really need to see the top of the receiver cover, which would underneath that scope. That's where the Russian arsenal marks would be. Chinese arsenal marks would be on the left side of the receiver opposite the bolt handle.
Gladly will accept any help with this if someone else wants to offer it...
