I looked at the marking under bright light and high magnification and the numbers on the barrel flats inside the oval are 20-70 on both sides. The small alpha does not appear at all, but the P.V under a bar and squiggle are the same, but there is a * over an AH and vertical bar over three chevrons that are different.
