Here's another possible Chinese made bayonet. I suspect that it's for Chinese made Type 1 rifle. However, I don't have a Chinese Type 1 to test. The closest I have is a Chinese used German Mauser M1904 and it fits well on that rifle. Here are the detailed photos of the bayonet, scabbard, and how it looks on that M1904. The detail of the rifle can be found here.
More photos to come.
