You are correct he's the one on the right in that photo. His name is Fred G. Yerkes. I have relatively strong circumstantial evidence he may have been involved in running guns to Cuba. I was going through a box of old photos while my father was still living and discovered an albumen of the Commodore tied up at what appeared to be docks in Jacksonville. I found three more photos which turned out to be the Dauntless, the Three Friends and one of William Randolph Heart's steam yacht Vamoose. My family was in the hardware distributing business and owned large warehouses built over the St. Johns River. To thicken the plot my great grandfather was the founding partner of Yerkes & Plumb which later after he sold his portion became Fayette Plumb company. Plumb axes and hammers are still made. My great grandfather Jonathan Yerkes was a member of the same Masonic lodge in Pennsylvania where the plots to run guns to Cuba were hatched. Henry Disston another hardware manufacturer was also a member of the same lodge. Both retired and moved to Florida. Henry Disston was a known supporter of Filibustering the term used for running guns to Cuba. Who knows?   

I"m posting additional photos of my grandfather's Medals and will post a few more photos of the Krag later today. BTW the muzzle cap does not appear to have been stretched or if it was there are no stress marks on the metal.
