How can I tell which make of nozzle this is, and where it was made?

If I wrote them down correctly, the numbers on my nozzles are below.

ANOSD240.

I don't recall if they had the “/” after the 240 or not. I didn't know to look for that until after I had put the injector back together.

They also had the letters FD enclosed in a shield looking symbol.

All the posts I've searched say it should actually be DNO, not ANO, so I'm wondering if I mis-read them.

What is weird about them is I did not see the cross drilled pintle that I expected. It seemed to be more of the flat type, as under the magnifying glass, I could see a slight flat edge on the side of the tip of the pintle. But the pintle also had a hole in the middle of it.
