[Lugerdoc]

Ron is correct about the 1890 law, although in 1923 they modified it to require the marking to be "made in ---) followed by the country of origin on all items imported for resale. Therefore you'll see luger mags imported without pistols marked "Germany" and unmarked US MILITARY test lugers with no import markings. The importer marking were again changed in 1964, requiring the name (or abreviation) of the importer, location, and caliber to be added to the country of origin. This was left to the importer to handle, so I know of many that bypasted that step. Also know that was not required of individgles bringing personal property or FFL holders importing items for their own collection (not for resale) on a Form 6. The only way that I can justify Interarms and others getting away with importing tons of WW2 surplus items into the US without marking them, is that they were also supplying them to may countries militaries and just "forgot" to mark the items sold domestically.
