Hi Reid,
this is doubtless a blockade runner of the confederates. It is possible, the scene may be Wilmington harbour, N.C. From this strong protected area many blockade runners sailed to the neutral harbours of the Bermuda and Bahama Islands.
It's not possible, to eruate what singular ship is engraved, because blockade runners, mostly build in Britain, had many similar construction details - characteristics are the two funnels fore and aft the paddlewheels like the blockade runners "Phantom"and "Hope".
