Finally got the pics to load. The top piece is a mystery to me. It generally resembles a m1845 British boarding cutlass that has been realtered or it is another one-off copy for private purchase use. Note the corrigated iron grip and odd construction of sword. The blade on this one is straight for almost int's entire length until the end, when it makes an abrupt curve (saw a few blades like it in Neumann. Rev War era??) This earlier blade was set into the fully constructed hilt and brass was poured into the empty space to set the blade. Opinions on this over the years have been varied; earlier period 1810s sword, m1845 knockoff, parts sword, etc. Opinions here?
Second piece is definitely a m1845 naval cutlass cut down and refitted in a Malay scabbard...can you say "pirate"
Pictured here for comparison of iron ribbed hilt of later mid 19th century construction...
