Hi Sajen,
nicely picked up!! I think the corrosion is just lying on top of the metal. Dont think you have to woory about that. On the contrary the metal bands on the second kris on the grip will give you (us too?
)a nice surpise! Possibly a silver alloy (hopefully).
The scabbards will also be restored? Ai that will be a more serious 'job'.
Also; seen the two iron nailstubs on top of the second kris grip there may have been a rounded (ivory??) top attached originally.
Whats the age of these; around 1900? slightly after?
Congrats!
