Hi Corwin,
As you may know, there is quite a bit of information available about the life and times of Hulse. I have not seen any images of him late in life, but do have a scan of a carte de visite of him with fellow raider Lee McMurtry. The image will appear, with McMurtry's profile, in my forthcoming book, "Faces of the Confederacy: An Album of Southern Soldiers and Their Stories."
I am interested to learn more about the tintype and revolver. Any chance you can send a scan of the photograph to me at rcoddington@facesofwar.com?
Regards,
Ron
