I found this rusty piece when we moved to a new property. I was looking through the barn and came across it. I hope some experts / hobbyists are willing to have a go at identifying it for me. Also, a feather, the one shown in the pictures, was found inside the handle. If any of you have any information on why a feather would be in there that would be really cool. The feather is bound at the bottom with a green tape of some kind, and it is preserved very well. There are no identifiable marking on the bayonet. If there were then they are probably rusted off by now. Thanks.
