That's kind of what I thought, but at least the stamping looks neat. I was raised in a house in Rockville, MD. that was built in 1948. The wastewater pipes in the crawl space in the basement were marked "Krupp". I assume they were confiscated during the war and purchased as surplus by an American company and sold to budding postwar construction companies. This year, I shared a duck blind at a private club on the Lower Potomac with a gentleman who turned out to be the son of the man who built that house. Continuing the coincidence was the fact that our mothers had worked together in the same government office in Washington during the war. They had renewed their friendship when we moved into the house in Rockville in 1948. It also turned out that our fathers had shot ducks together at his dad's club in Dorchester County on the Eastern Shore. Small world.
