I rolled the dice and bought the earliest one the shop owner had which was a 34k serial number. I spoke with him on the phone for a good amount of time about the story behind them and what rifles he had. Long story short, he bought them off someone who purchased a crate of sks's back in 1987-1988. The original owner paid $69 per rifle.
I received a refurbished 34k serial Chinese sks. The stock, bolt, gas tube, piston and rear sight were not numbered. The parts all had the same font. The entire rifle was caked in cosmo and I am leaving it as such. The rifle reminds me of a commercially made sks. It looks like it was a very late refurbishment intended for commercial export. The bolt and carrier have that "brushed" chrome finish, unlike the early polished chrome finish. The rear sight is the early "n" marked one. The rifle came with a sling, green star oiler, and cleaning kit in the buttstock. The owner has more available, 7 mil's latin prefix and a 200k one.
