An Albanian star is a plausible, but difficult to prove or refute, hypothesis.
I guess the star marking would be analogous to the star marking on Italian Carcanos imported from Albania, but those stars were always on the wood, IIRC.
I’m not aware of Yugoslavia providing aid to Albania. Doesn’t mean it didn’t happen. There was certainly aid from the USSR early on then greater and longer lasting aid from the PRC. A few Yugoslavian SKSs finding their way into Albanian hands unofficially is not far-fetched during the break-up of Yugoslavia, Kosovo Wars, Albanian economic collapse, etc. If Yugoslavia had provided significant numbers of SKSs to Albania as official aid, I think they would have turned up in the cave caches with the Chinese and Russian SKSs and would have been a target for import by CAI in 2012 since the Yugoslavians are on the C&R list.
