That is a kanji NOT an anchor!

Thanks Jareth ... I guess I was not clear enough in my earlier post:

The kanji within the circle (私) means "I/me" or "private/personal". I think in this case it identifies the binos as private purchase, not military issue.

I'm no expert, but am just throwing this out for discussion.
