Default Re: "Foreign" marked B9A valves

That could be verified by looking at the 2 lines of small symbols along the bottom side. One sign of being made in Eastern Europe could be the omission of those lines. If the lines are present, the first character of the second line translates to the original factory within (and sometimes outside) the Philips group.
