Just for the heck of it, I have REALLY REALLY tried to find a Skull and Bones connection, but can't. There might be a connection. I just haven't found it yet.
On the other hand, another mystery: I also can't find a rendition of the A/Alpha that resembles the one on my piece. Even old Greek and Latin Alphabets have the center line as a simple horizontal bar connecting two diagonals just like the one here: A
Mine is basically a large upside down "V" with a small right-side up "v" inside of it. So now three options:
1. Perhaps mine is really the Greek letter Lamda, which is basically an upside down V, but I am having no luck finding.
2.Another Euro-centric alphabet that has an A similar to mine. (I even looked up Cyrillic. No luck.)
3.That middle letter really is just an "A" with some creative license taken and I am making much ado about nothing.
