I still defer to our uniform experts, but I've decided to play
devil's advocate for a moment.
Are we're sure these pants are Civil War era ? military even ?
While we all know red piping is the color of artillery, I've never seen the dark tape along with the small red stripe.
Could these be a part of a local band uniform perhaps ? or part of a religious/fraternal order ?
Again, I have no idea . . . just an observation.
