I just recently picked up a Chinese type 56 fixed stock stamped ak with red fiberglass furniture. There are no importer markings on the rifle. The trunnion has "56" and a 6 digit serial number. No arsenal stamp. No "Norinco" or "polytech" stamping. It is definately a 1.6mm Chinese receiver with "S" and "C" selector markings. No evil third pin hole. The original box shows the rifle was shipped to the retailer in 1987. The instruction pamphlet is a Norinco instruction pamphlet.
I'll have pics up soon, but picture a Clayco fixed stock with red furniture and no markings on the rifle other than the selector and trunnion and that's what I've got. Any info would be greatly appreciated.
New info: chicom47.com lists this as a very early example of a 56-S3 before they were marked as such on the trunnion. The import mark is on the barrel "IACO SAC CA".
