It would be interesting to know some numbers
Somewhere, I remember reading there was 3 pallets brought in... No clue on how many that would equal, I'm guessing a couple hundred. I don't see them as being that rare.. they seem to show up more than the... Albanians or Romanians, but also in lower numbers than than Russians, Yugos or many other Chinese.
More like uncommon..so
I could see possibly 3 conex boxes... legally, weight wise... you could haul roughly 5050 8.5 pound SKS's down the road in a conex box with "no" packing material, thats between 42000 and 43000 pounds of SKS rifles. Figuring in some pallets and shipping material.. with 3 shipping containers.. you end up with a lower number(shipping material equals weight), so somewhere between 9,000 and 12,000 SKS's spread between 3 boxes. The number could be a little lower if they were shipped in the 10 rifle wooden crates.
Even at 9000 Public Security rifles..... your at almost twice the number of Albanians that's estimated to have been imported and still just a very small fraction of the Russian/Yugoslavian/vast other Chinese rifles imported.
