This is the second DDO
I found in box 3 of 4. What's interesting is it's the same variety I found in box 2 of 4, so now I have two of them.
This appears to be an FS-50-1974D-101 (015). It is not quite as sharp as my first one, but the doubling is still pretty strong. As always, if anyone disagrees with my assessment, please let me know.
