I have one from the Albanian import batch with a large "CAI Georgia VT" import stamp on the receiver. Makes me wonder why these got the big receiver stamp but the Type 56s imported at, or near, the same time got a more discreet stamp on the barrel.
My other is a probable bring back, no papers, but 1960 production, has the look, with no import stamps. It's posted in the Mosin section. You may have seen one of these.
I recall (not 100% certain) that Navy Arms was the sole importer of these prior to the Albanian batch. They often used a very discreet N.A. Co. Stamp about 2mm high at the wood line on the receiver (typically on the right side). Quite easy to miss and could have been slightly below the wood line. Many of these were in very good condition.
