While I agree with you in general I have to disagree when it comes to the kris blade, the overall style and the separate gangya I personally would place at the end of 19th to very early 20th century. I guess that an antique blade with rotted fittings get a new dress at the time of the mid to second half of the 20th, the current hilt and scabbard are typical for this time.
I know this practise from Indonesia, for example you can find very old blades in rather new tourist fittings (Bali).
I am nearly sure that we see an antique blade here.
