I recently acquired a Chinese made SKS and trying to decipher the exact place it was produced. The gun is marked with a triangle with numbers 906 inside it after that it has serial number 1720115 says Made in China by Norinco CSI ONT CA. I have an excellent book that is for collectors with tons of info. From this book my best guess is the gun was made in 1957 and in #720115, but 20115 is the only number stamped on everything else. Also I find nothing about factory 906, I found 96, but not 906. Anyone have a better handle on this for me?

I also just rad that in pursuant as of 1990 it is illegal to install a bayonet on the Chinese version SKS. WTF? All the others made somewhere else it is ok. According to the law if installed it make the Chinese SKS an "assault rifle". Oh Duh! Anyone got a handle on this too.
