Would anyone like to weigh in what they think this might be? I’m seeing this symbol quite a bit on 19th century documents (US Territorial period and later) in New Mexico. I think it resembles a masonic symbol . . . .
They usually appear quite small on the back of a document (where there is little or no writing) or at the bottom of the last page. The one I have below is the only one that I found on the top of the first page.
