Have been reading the post on this mystey badge with great interest.

I do have one question, could there be some sort of Clergy connection.

What the arm Dexter is holding, it looks like 3 cros'es ( forgive my spellig ) and it looks like they may be on a staff for the bottom extends below the hand.

I enlarged the picture as large as I could and noticed these things.

If there are any people with knowledge of Church symbology they might have a clue.
