keris with prussian hanger hilt

[rumpel9]

Hi, everyone.
Some time ago I bought interesting keris with hilt from prussian infantery habger. Keris blade has very good quality, you can see at the pics.
Before I have seen keris blade with european plug bayonet hilt in Stocholm Royal Museum of Arms (bottom pic). At the museums catalog it specified as a keris.
It would be very intersting to see comments about it from forum members.
