Need help to identify this mysterious knife / trench knife

[king kong]

I'm looking for help if anyone out there can help me, On this mysterious knife
I know its Bulgarian, I have included in the photos another knife almost identical that was for the Bulgarian red cross which as been cut down, This is a mystery to me why they are different

[bigmacglenn]

I can only speculate that we're looking at a Field-Made Fighting Knife...Bulgarian Items are totally out of my area of expertise, hopefully someone can add more information...
cheers, Glenn

Thanks Glenn, it's possible a ww1 Bulgarian fighting knife then

Very poor overall. Who knows when it was
made. I'm suspicious about all the filler
and 'aging'.........
