I was wondering, but it does have a complete doubled D. Its hard to see in the picture you can see the remnants of the complete D on the left side 1/4 way down and reemerging at the bottom and to the left. It shows perfectly under a loop. My magnifier is not the best. It's why I was seriously considering a 42/1 also. By the way does anyone have a recommendation for a USB camera with 1-80 power for taking great pictures.
