I'm thinking about buying my second SKS and would like know what was the original finish on the metal ? The first one that I bought was a very nice blued or black, hard to tell, I think black finish. I hear about a nice satin type finish and the infamous bbq finish. Are there specific years for these finishes or the result of different factories refurbishing and how good are they ? I suspect the blued is best, followed by the matt finish.
