15003xx
I think it is factory 946?
3rd year of production, 1958.
(Blade bayo, side mounted rear sling swivel)
Not my system. A few guys over at sks-files.com uncovered it.
I think the system applies to the Type54s and the early AK56's. I'm strictly an SKS guy, though.
# 310829xx?
Is that the right serial number?
Can you post a photo of the serial # and gun.
Thanks for quick reply. Do you have any info about factory 946? Rare, common etc? I bought mine cheap a couple years ago, but seen someone selling one recently on the EE for 600. I'm guessing he was out to lunch, but wouldn't hurt to ask.
Triangle code looks to me like /660\ or /060\ or possibly /160\ I can’t tell, serial is 22000578
post a photo of the arsenal stamp, or try here to see if the stamp is on this list:

The 22 prefix suggests that it is a 22nd year carbine (1977)
T5 6492
All the numbers on the outside match, including the magazine (other than laminate stock). Bore is excellent if not new. Blueing is mostly good, small discoloured spot on the rear.

That's not a Chinese rifle.
It's Soviet. The first two characters are "TБ" from the Russian Cyrillic alphabet, and the last character "Д" which indicates a 1956 year of manufacture.
