Brazilian 1908. Most likely a Czechoslovakia production but does not carry the export mark of a Z in a circle. The only marks on the bayonet is the SN 5585 on the rear of the quillion. The scabbard is leather with a metal finial and on the frog lug is stamped F1 = Fabrica De Itajuba, the Brazilian state arms factory. This identifies the bayonet as a Brazilian made replacement scabbard.
