I think Willi Vanilli hit the home run! That photo on the right is the article. The one you have is missing the tip but one would hope that the tips would be replaceable. Finding something like this in the middle of nowhere wouldn't be that odd for war artifacts. The French and Indian War was fought largely in the wilderness and so was the Revolution any time we could catch the British in there. When cavalry outfits were doing recon they traveled in forests or at night to stay out of site. One such expedition was Stewart's action north of Gettysburg in a time that his troops were badly needed in the battle.
It was also common that cavalry detachments carried medical staff with them that also acted as combatants. One such field surgeon was Dr. Russell who rode with Mosby. He spent his last years living in a hotel in my home town. He was once asked why he never participated in the reunion celebrations. He said he had ridden into battle, with Mosby, three times in the area and that every time he saw a certain soldier hiding under a powder wagon. Every time he'd gone to the celebration he'd seen the same man up on a wagon giving a hero speech!
