Yes, I found it last Spring in a Civil War Camp occupied by the Army of the Frontier.
Great Eye Spats.
I mistook it for a Fancy flat Button.
That button is Banner in my Book.
I have never heard of Gempler's but I looked it up online and it looks like something I might try. Thanks for the information
