An item such as a razor was owned by most every man back then including men way richer and poorer than Wild Bill.
To think a gun proclaimed to be from him is sketchy, I think a lot of provenance was lost.
I have some much nicer penned ivory scaled razors. One was Henry the 8th's and the other was used by Elvis!
I thought that you were going to return Henry's and Elvis's razors to me after you gave them a test shave.
