Miller.. That i really cool so far we have 3 of the.. I contacted American Digger magazine to see about getting an ID on the button.. Here is what they said
I have never seen this button before, so I forwarded it to William Leigh, our button expert. To me,. it looks like one of the iron pants buttons that we occasionally dig out of Civil War & pre-Civil War site, almost always 4-holes, iron, occasionally pewter or copper, & about 5/8" diameter.
William Leigh responded to me last night and included is his comment on the item. He has seen and handled about as many buttons as anyone in the hobby.
Hello, I bought one off ebay within the month...had not seen one before and wanted to examine. I don't know how old they are...I guess we will know soon, if they keep turning up!
