It's a WWI German "Butcher Blade" that has been cut down, along with the scabbard...
I think Glenn has it, looks like it's been cut down into a fighting knife!...
It's a wasted trip baby. Nobody said nothing about locking horns with no Tigers.
I'm Spartacus, not really i'm Paul!...
glenn is right ww1 german bayonet.
Turkish modification perhaps ?
I see no Turkish Markings to suggest that...We do encounter these Cut-Down Blades re-issued to Weimar-Era Reichswehr & Polizei, BUT they are well-marked pieces whereas this is not...Nor do the reissues have such a remodeled scabbard, which appears field-modified...
I would speculate a field-made Fighting Knife...That scabbard is quite interesting...
Agree with the guys, will add that it looks like the remains of 17 on the spine indicating manufacture 1917 also here's a picture of what looks like the makers mark which I found on the net if it helps.
Don't know why the cross guard has been buffed so deep and a number stamped on it. perhaps someone else can help with that.
this is a very known turkey M35 bayonet made out of a S98/05 from the military assistance from the german empire to the ottoman empire 1917 - 1918.
Typical rework after 1935.
The most S98/05 were reworked.
