Maybe it just my eyes, but I think your arrows should be on the west side of the five (straight stalk). The five and the one look to me to be moving in the same direction corresponding to the doubling seen under both digits.
SPP-Ottawa, thank you for mentioning the 70th ed. Charlton Catalogue... I have older and newer, but not the 70th edition. I have seen your reference of it before and decided I should have it in my library. It took me a bit to find it, but I did and have already ordered it. Thanks again!
