Tulwar Boarding Cutlass?
 

Years ago, I purchased four swords off ebay. All four had the exact same cast brass hilt. Similar to a British Brunswick sword bayonet, but with a full "D" guard. Very robust. They all had large, wide Tulwar style blades. Two were plain back, and two were hump-back. (Too lazy to look up blade style names) All four, had the same maker mark on the blade. All four had traditional leather covered wood scabbards. No suspension rings. What wuzz they? I have pictures in my old computer, but will have to get a flash drive, and find a monitor to pull them up.
