Found this gentleman on a tintype I recently acquired. I like old photos but I'm not up on Civil War artifacts. Trying to figure out the uni -- the hat looks like a kepi with crossed cannon, the jacket has sleeve braids. What's up with the chest embroidery? Is it Civil War? Union? Are those 2nd Lt. epaulettes? I've tried looking it up on-line but I don't know enough uniform technical terms to narrow the search.
