Hard to tell from those pics. There are 9 DDOs listed here http://www.lincolncentresource.com/doubledies/doubledies.html you check it and see.
If it is , it is either a -003 or a -006, and my money from the photos would be the 003. But a better close up of at least a couple of the letters and the date would help finalize. My eyes are only good enough to say IMO. Jim
