Triple stamped wideframe ek2? Very very strange cross...

Here's a "WB" or "WR" on the small ring of one of my "24s."

George, amazing , I will also take a good look over there in a minute. What would it stand for?

I don't know what it means. But here's yet another such mark on the large ring of an EK 2 that was sent to me for examination by a Forum member. It was also a wide-frame version.
