US Army Civil War Musket Rifle Socket Bayonet - Reproduction

Description

I'm not an expert in military items.
I say Repro because the Estate sale I got this from had a few other repro items.
The blade is not sharp at all.
Seems to have been cast all at once, as the screw on one end is not removable.
Please see pics and decide for yourself.
Very clean.
Please see my other valuable vintage collectibles for sale.
Thanks.
