The hilts are very crudely made and assembly is very sloppy.
The way the disproportioned hilt of the second sword is riveted is appalling, with the rivets protruding like bad jokes.
In my opinion they are modern, low end, wall-hangers/tourist stuff/fakes (albeit the blades might be functional).
Regarding the "aging" of the second sword... well... keep a brand new sword unoiled for a couple of years in damp environment and you will get that "aging."
I hope you didn't pay much for them...
