Civil War US M1855 musket bayonet.  Could be an M1873 as well so please use your best judgement.  This is an old one for sure.  Right from an estate sale.

21" long.  Condition consistent with an antique bayonet.  Some corrosion etc.  SEE PICTURES.

I HAVE MORE ANTIQUE BAYONETS AT THE BEGINNING OF THIS LISTING.  PLEASE SEE MY OTHER LISTINGS.
