These two just ended on e-bay.
The first one seems to be either French or Turkish bayonet converted into a Yataghan ; the handle looks Greek to me.

The second one looks completely original; the quillons remind me of Piso Podang, but the handle looks Hungarian. I am not very good at bayonets; any ideas?
