... some people are not really serious ;).... See here : Item number: 280236648329 (ebay) .... there's a lot of bad informations .....
Firstly , the scabbard is not correct . WarninG guy's
The photographs are very dark, but I do not believe the blade has a fuller. I think the seller might not know what a fuller is. Besides, only first contract bayonets had the fuller and they all had bright blades. The one in the photo definitely has a black oxide finish.
