Unfortunately, the Chinese did not release any arsenal information to help identify your gun. The best way to narrow down the era of manufacture would be to check out the features that are different on early versus late models.
Since it has a spiked bayonet, it is at least newer than 1965.
Is the barrel pinned or threaded into the receiver?
Is the trigger housing made from one milled piece, or stamped together from two pieces?
Also, the duckbill mag is not original. They came with internal 10 round mags that were not detachable without taking out the trigger group.
You have a Factory /0223\ Norinco SKS, the three Chinese characters were added to the receivers after 1963. However it's about impossible to exactly date your rifle as far as year of production because only the factory /26\ rifles can be reliably dated. The spike bayo started to appear on the Chinese SKS around 1965 till the end of production,some other features that changed later on were pinned barrels vs. screwed barrels with locking lug and stamped trigger housings.
Before purchasing an SKS with a "duckbill" magazine you might want to read the tacked thread on those magazines. It's at the top of this forum.

the markings on the receiver are /22\ (with a smaller 0 in the triangle on the left of the 22 and a 3 on the right), chineese markings i can't describe and either a 21 or 27 before the rest of the s/n.
all numbers match. has a spike bayo and the duck bill mag.
thanks for helping.
At first I thought you had a Arsenal /22\ vary rare, I have only heard of one from a guy on another board and seen 1 in person...... and yes it does exist.....
