From the May 11, 2016, BBC News "new image of Clyde-built ship used in America's Civil War" by Steven McKenzie.
There is now a sonar mosaic of the Agnes E. Fry blockade-runner. The article contains this.
There is also a North Carolina Department of Cultural resources of a deck light and what looks like the handle of a homemade knife recovered from the wreck.
Specialist divers from the Charlotte Fire department and sonar experts from Nautilus Marine Group assisted in the mosaic.
The Agnes E. Fry was launched with the name Fox and ran aground 27 December 1864 while attempting to run into Wilmington, North Carolina. Since this was between the two attacks on Fort Fisher, it is doubted that much in the way of salvage was done at the time.
The mosaic photo of the wreck includes two possible sponsons, boiler fragments, decklight (recovered) broken hull plating and frames and I-beam frames, smoke stack sections and outer hull plating.
