Thanks for your thoughts. I have been looking at some info on the Syrian made fakes. They are very good indeed. Apparently it was just one man or one workshop where all of the good fakes were coming from.

Probably the best thing for me is to take it with me to Tucson, and let some people look at it up close.

Either way, I only paid a price for it that a good fake would cost. So if it is fake, not much is lost and knowledge is gained.
