This sword is most likely from the late 1800s, possibly early 20th century. The name of the manufacturer can be seen on the blade: Horstmann. The knight’s head on the pommel and the ivory (probably celluloid ivory) handle are pretty standard for fraternal ceremonial swords of this period. Most likely not a Knights Templar sword, of course. I have not been able to pinpoint the floral designs on the guard. Looks like a rose on one side and a cross on the other. Help with identification will be much appreciated.
