A total of 46 allied nations use the TOW, and it is co-produced in Switzerland.
Notice in that photo, that the markings are in English, and the production date is shown as 2001. The Swiss would mark them in German, French, and Italian.
Production for other nations might not use the same packaging or markings as those produced for US forces. The storage/shipping boxes look kinda old fashioned compared to those I've seen for recent (and 2001 is very recent) US storage cases for other weapons.
I'd be real curious to hear what the MI types ultimately have to say about those weapons.
I am not sure that they would. The Swiss have more or less officially adopted English as the region-neutral language of choice in recent years, in some sort of language normalization effort. For the export market, it certainly would make sense for the markings to be in lingua franca (sweet irony).
