Getting back to the original intent of this thread:
Last time this came up with the EMF Alchemista, the Authenticity Committee simply could not find an original documented, so it was basically dropped. No action taken, no Approved List or Unapproved List was modified. So, Johnson, in one respect it is a grey area. On the other hand, being in the grey area, it is incumbent upon the person wanting it to be approved to provide the documentation from the 19th Century and petition the AC, not the other way around. I am sure the AC would be happy to consider it again, provided documented evidence that they existed. Having seen just one would not sway me as a member of the AC. Could be one person's adaptation. It's an undocumented issue like the bird's head Colt SAA. There were 5 special ordered from Colt by one man and presented as gifts to 5 of his closest friends. If you can tell the name of the guy that special ordered them, and where they went, perhaps that would be revisited.
