Thank you, stampvirgin.

Although, if I had known how important the edges of the oval frame are, I might have done things differently on both this and more importantly my #9, just to be sure.
I got my magnifying glass out tonight for the white speck, and found nothing there. So I put the stamp into a different mount and rescanned it ... and got a white speck at 2 o'clock on the circle of the postmark. So I huffed and puffed and after several attempts finally got this. What a relief ... no sign of the white speck ... but whatever it was had to be pretty determined to hang around since it didn't fall off when I put it away last time and then got it out again tonight.
