I have an antique Kentucky rifle in my collection which has numbers faintly, but nicely, engraved on one of the guard extensions. As follows:
6 20 25
For years, I assumed that was a previous owner's identification system. However, since rifle would date to the 1820s, I recently began to wonder if that could be a date of completion that the maker put on it. My efforts to determine whether such numerical notation of dates was used in the 19th century, as it is today. Any suggestions?
