I don't see that this one has been discussed before. There were 6600 Model 1841 Naval Cutlasses made between 1842 and 1847. This is one of 2500 that were made during the first year of production. This one must have remained untouched for a long time, based upon the aged patina of the brass hilt. The blade was almost black, with numerous rusty spots. I did use a copper scrubbing pad and oil (copper being a softer metal will not scratch the blade, but does a decent job on rust and grime) to remove the rust, and then coated the blade with Renaissance Wax. Made by Ames, these cutlasses are found with the Springfield and Cabotville addresses. If you are lucky enough to find one with a scabbard, the scabbards come in two styles. The first type has a brass throat and tip like 1832 Foot Artillery Sword. This one has the second type scabbard, with copper rivets like 1860 Naval Cutlass scabbard. I read someplace that these second type scabbards were Civil War era replacement scabbards for those Model 1841 Cutlasses that were still in use at that time.
