It was not made for the Italian market, as it does not have sling swivels on it.

Really need better pictures of the flats to see the markings.

Krupp is a well known German steel maker who supplied a lot of barrel stock to the gun trade. You can find Krupp barrels on all sorts of guns, including American.

If it were a Bernardelli, it would bear the name.

It appears the seller values the gun more than it is worth.
