(ed. Just to make it perfectly clear all four were once, or are still now, in the Cassin Collection, New York)
I have created a composite image of 'Baluch' pieces you have indicated: admiration for, and, a belief that they are among the oldest 'Baluch' you have encountered.
I think such a composite might be helpful in providing those that have been puzzled by one or more of the individual images get a better feeling for what it is that you are seeing.
In any event, I have enjoyed it.
