No not a DDO, however, potential struck through grease on the back- around the edges. I see what you mean by DDO, with the L and T of LIBERTY, but, I think that might be machine doubling. Wait for further replies.
Anthony, the key I use for this one in "IN GOD", and the last photo showed the area, but it was somewhat blurry, out of focue or vibration with the camera. Find a block of wood or something vertically solid enough that you can get a sharp focus if you can. Probably not, but very small chance on it. The rest as mention, probably MD. Jim
