Now, regarding the Spencer Rifle Socket Bayonet, I Emailed the following to an online Civil War dealer:
"I have been visiting your web site, and was hoping you might be able to provide additional information on the Sharps/Spencer Socket Bayonets you have listed.
I own an original Spencer Rifle and would like to add an original Spencer Rifle Socket Bayonet to my collection. According to the Roy Marcot book,
Spencer Repeating Firearms, "the Sharps bayonet will not seat on the Spencer barrel." You list your socket bayonets as
"Sharps/Spencer", so I'm not sure they will fit on my Spencer barrel, or do you know otherwise?"
