no im not talking about modified mak-90s. all those letters and numbers the OP has posted i must have seen 3 dozen times over. The numbers 56 (dont remember the S), Norninco, that weird triangle thing, and NY are all a familiar site to me. as for the red fiberglass ones your right, that one i have never ran across. a heavy ass norinco with red fiberglass furniture would defiantly get my attention since all the ones i have seen, as pictured by OP, are all wood, or folding steel stock. im not saying people are wrong in saying its valuable. but a standard AK thats worth 1k, just because its rare in the U.S. is like saying a standard Gen 1's Glock 17 worth 2k because they dont make them any more. maybe im being close minded, but old, rare, used in war guns are the only reason a standard made rifle will be worth more than it should be.
but be the case that it is, i will defiantly be on the look out for fiberglass furniture norincos that are being sold under 500. not to get off topic, but anyone got quick info on Maadi's? those i havent seen too much and i cant seem to get straight information on like Yugo's, WASR's, Maks's, or Norinco's.
