44 AMP- I think you answered most of my question. Thank you. I was referring to old Korean and prior conflicts. In my particular case it is a WWI Hungarian Manlicher without import stamps. But I often see older Luger, P-38's, Mosin, etc... That do not have a import stamp. i was just a bit concerned about putting them in my collection.
