I would also add that due top the cheap prices on surlpus such as offered by say Banerman or Stokes... "honor guards" and "marching band color guards" often made use of CW issue items. And "improved' upon them by painting them white for parades, or such things as painting the barrels on muskets silver. I have seen a few nickle-plated M1863's as well.

Not a real Civil War reenactor, I only portray one on boards and fora.
I do not portray a Civil War soldier, I merely interpret one.
