From the images provided I don't see a match yet. The CONECA 1984 1c DDO-006:
http://www.varietyvista.com/01b%20L...4PDDO006.htmBut the die crack is wrong. The one on that site is a Stage C LDS. So I doubt that it is that die number.
The Wexler one doesn't look like a match to me from what I see in the images. (die state can alter a die a bit)
So you might want to consider sending it in to one or both sometime in the future. You might try images first. Try to get images that would be helpful to see if they are interested to look at it or not first. They may see something we don't from other images they may have of their examples. It might be a new die. Try taking images that they are showing on the site. The Variety Vista site may want to see if it is a different dies state than they already have. That is what I would for this one.
