Hi J Greene.
As for the first sword, it appears to be a genuine blade with the remains of a koshirae. The snap fitting is not unusual for the leather combat cover which was added for use in WWII. The hilt is missing menuki but the fuchi and kashira are genuine as is the tsuba. The blade does not seem to have lost much of its tip so perhaps worth showing in hand to someone who can advise you but it seems to be a shinto sword, not a showato. As far as I can tell your link has images of the fittings but not the blade, post some more of the blade, as clear as you can, and you might get some more opinions.
Have fun.
