24-Pounder Dahlgren Boat Howitzer at the Erie Maritime Museum
24-Pounder Dahlgren Boat Howitzer Number 86 is displayed at the Erie Maritime Museum in Erie, Pennsylvania. It is a standard US Navy Boat Howitzer. However, it is marked “For Treasury Department” on the breech - indicating that it likely served on a US Revenue Service Cutter.
US Navy 30-Pounder Parrott Number 307
US Navy 30-Pounder Parrott Rifle Number 307 is displayed at Trophy Park at Norfolk Naval Shipyard. It was manufactured at West Point Foundry in 1864 and weighs 3,500 pounds. According to the research of Wayne Stark, Number 307 did not see any shipboard service in the US Navy, however it was loaned to the Treasury Department from 1864 to 1876. Given that a stereotypical armament for US Revenue Cutter Service cutters during this period was a single 30-Pounder Parrott and two to four boat howitzers, Number 307 may have seen service aboard a Revenue Cutter.
