Thanks for the good leads, everyone. Octagon Barrel, I will post some photos of the display.
I already thought of an Avenging Angel. I am having one built right now for my own pleasure. I have also been loaned by other club members the following: Remington .31, Colt 1849, Colt 1862, snub-nose 1860 Army (ala Stoudenmire), a S&W #2, a Colt .22 single shot, a Remington .41 derringer, and a Philidelphia Deringer like the one used on President Lincoln. Got many others that have been offered for the display.
I appreciate everyone's help.
