All things considered...
#1.. it's Albanian #2.. it seems to match #3.. ain't a whole lot of them in existence.... all this, equals don't sweat the small things like fonts. If you snagged it for 600, thats even better, its a good deal considering what I've seen some on auction sites sell for.. I have one with a Yugo bolt and another with a Russian top cover, so they can be found in many different configurations....
As for the sling, typically Albania had their own native design, which can be very difficult to find and usually expensive like the Romanian leather sling, yours looks Chinese, which works too given their relationship at the time. One of mine came wrapped with a old Chinese sling that looked and smelled like it was drug through a sewer and then someone died on it.
Flip the bayonet to it's correct position, sniff the wonderful grease and enjoy it
