The original arm is on display in the museum at the Gettysburg NPS Visitor's Center. I made the comment to another Skirmisher friend of mine that was touring the museum with me:
"Make a repro of this one and try to run it past the Small Arms Committee, I can already see the big SAC "REJECTED" stamp on the repro!"
Actually, that Richmond is a good example of the Confederacy's "repair or rebuild and recycle" anything that shoots philosophy. I just wish that N-SSA rules recognized that fact.
