Hi all. II came across a demag / crank handle bayonet for sale (pictured). The seller hasn’t set the price yet and I’m not positive that the bayonet is real. I’m wondering what are the easy identifiers between a real and a fake. So far I noticed that his bayonet has a stamping which starts faded on left and becomes crisper as it goes right. This isn’t what I would expect, but I’m not a demag expert either. The scabbard is black with some rust and has the loop hanger/frog. The handle is not blued, it has some type of dull green paint on it but I don’t know if its original.

So, any tips / advice? Also, what is one worth in average worn condition?
I’m having trouble finding any authentic ones sold or for sale because
I’m not sure if I’m seeing worn fakes or the real deal when I look. Thanks
