Again, silver was often used as a display of wealth, rank or status on many swords, particularly as it's regarded as a "clean" metal, spiritually, in the Muslim faith.
Many warriors added to their swords as their station in life improved, so it's not unusual to see silver newer than the rest of a sword, and keep in mind that swords were also often passed down from generation to generation as well as being highly regarded battle trophies.
I would suspect that more than one klewang was retired back to field chores when its owner was fortunate enough to come out the victor in a battle or war, aquiring a weapon that would otherwise be far beyond his means.
As to age, at least as early as the late 19th century and possibly as new as the early to mid 20th century, but would hesitate to state anything more than that, other than it's a very nice weapon.
